An hour-long second season opener finds Sabrina celebrating her 17th birthday - which means that besides presents, she gets her copy of the witches' handbook and instructions to study it for a forthcoming test. But she must also cope with her classwork (including extra algebra), her responsibilities to boyfriend Harvey (including baking cookies and making a poster of him for the school dance), her shy new friend Valerie, and Libby's plot to take over as editor of the school newspaper. Exhaustion causes her to fail her preliminary exam, and be sentenced to witch boot camp; and her aunts are not allowed to warn her about the more serious penalty if she fails a second time. Meanwhile, when Hilda and Zelda's 300-year-old bond matures, Zelda decides to switch from physics to chemistry and buy a top of the line "lab-top" chemical laboratory which naturally proves irresistible to Hilda, Salem and Sabrina; and Salem makes off with some of the cash to buy new cat toys and a meal at a sushi bar.

With Cupid's assistance, Sabrina plays matchmaker for a reluctant Aunt Hilda and her new, smitten Vice Principal, Mr. Kraft, in order to avoid detention for a controversial editorial she's written, and tries to get Kirk to fall for Valerie. Meanwhile, Zelda is in deep trouble when Hilda forgets to mail her postponement letter for Witches' Council Duty.

Forced to date others, Sabrina and Harvey try to ease the pain by double-dating - but Sabrina's witchly escort Dante has never been in the mortal realm before and has a very bad attitude about it, with unfortunate conquences for Harvey. Meanwhile, Hilda copes with a bizarre illness, punnitis, that puts a spin on everything she says and causes it to be taken literally.

Sabrina's psyched to get $100 for babysitting her cousin Amanda. But she realizes she's been underpaid when the little witch, who's too big for her breeches, turns her into a doll and holds her captive in her toy box together with everyone else who has offended her. Meanwhile, Hilda and Zelda need a break from each other, so (naturally) they go to a spa together, where they become rivals for a hard-to-come-by facial appointment that is supposed to make a witch look centuries younger.

Wondering what makes guys tick, Sabrina turns herself into a boy and befriends Harvey's social circle. But the hoax turns hurtful when Harvey reveals an interest in Valerie. Meanwhile, Hilda also partakes in the gender-bending antics in an attempt to get rid of smitten Mr. Kraft by pretending to be a possessive macho biker.

Angry that Libby is having a Halloween party that pointedly excludes them, Valerie blurts out that she and Sabrina are hosting the coolest possible party at Sabrina's house. When a reluctant Sabrina backs up her friend, she discovers that her aunt's new furniture delivery includes talking chairs and couches infested with talking termites; and when Libby's bored guests crash her party, she conjures up 10,000 Maniacs to distract her schoolmates, who assume everything that happens is a "cool" Halloween special effect.

When Salem accidentally swallows a "time ball" that transforms Sabrina's life back to the groovy 1960s, Sabrina initially embraces the peace-loving mood of the era, but soon realizes that women have come a long way in the last thirty years. However, when Salem refuses to cough up the "time ball," and runs away from home, Sabrina must locate her missing cat before he does any more damage to the 1990s.

A trio of bitter hillbilly witch relatives start a family feud over Great-Grandma's will which gave Sabrina possession of her magic book, beginning when they magically lock the Spellmans inside their home. Trouble is, Valerie and Harvey are visiting at the time, so Sabrina and her aunts must talk fast to keep the truth from them.

It's Friday the 13th, which Sabrina learns is the day witches can tell mortals the truth about themselves because everyone's memories will be wiped clean once the day ends. Despite warnings from her aunts about bad consequences, Sabrina decides she can trust Valerie and Harvey to take the news in stride, and grants them each a wish: Valerie gets to dance with Drew Carey, and Harvey gets to meet baseball giant Mark Langston. But there's inevitably trouble: Libby overhears the news and alerts both the PTA and the media. Happily, Valerie and Harvey save Sabrina's bacon, proving that they are true friends even though they will now forget her secret again.

Sabrina neglects a vital fact in her use of incantations: if she fails to consider a spell's consequences, there will be a ruinous aftermath. When she accidentally sends her aunts and Salem to Merlin's castle where they are held captive, it's up to the Quizmaster to teach Sabrina a valuable lesson.

Sabrina's anticipation of Christmas gets out of hand: whenever she conjures anything up, it turns out to have been taken away from someone else. Her aunts send her to Dr. Bell, who diagnoses a bad case of "egotitis" by summoning Sabrina's inner child (obsessed with getting presents), and call upon Bob to educate her in the true meaning of Christmas. When Bob is injured in the course of his duties, a horrified Sabrina discovers that he is really Santa Claus - and that she must now take on his duties as a subordinate Claus. Needless to say, Sabrina rediscovers the true meaning of Christmas by distributing gifts that make everyone happy, even Libby.

Mr. Kraft is still dating Hilda, and still boring her half to death. When he announces that he will be chaperoning the Westbridge High ski trip, Sabrina decides that drastic measures are in order: disobeying Zelda's ban on anyone else using her lab top, Sabrina cooks up a potion to make him think like a teen-ager. Unfortunately, Mr. Kraft turns into a particularly obnoxious, irresponsible adolescent, putting both the ski trip and the school into jeopardy.

Mrs. Quick assigns Sabrina and Libby to decorate the "Democracy Day" float together, but Libby's obnoxiousness causes Sabrina to cast a spell keeping her a safe distance from Sabrina. The Quizmaster intervenes, blowing the whistle on an illegal use of magic to solve problems, and reverses the spell so that Sabrina must stick to Libby like unwanted glue. When a desperate Sabrina struggles free, the spell has disastrous consequences: Libby is transformed into an incomplete jigsaw puzzle, and Sabrina has only a few hours to locate the missing pieces and put Libby together again. This necessitates a visit to Libby's home, where her cold, controlling mother makes Sabrina understand her nemesis a little better -- as does the discovery that Libby has an ailing grandmother to whom she is devoted. Meanwhile, Zelda tries to find a miracle cure for disease but winds up inventing a miracle cleaning fluid which Salem and Hilda promptly steal and market in the Other Realm, oblivious to the unfortuna

Sabrina comes down with a case of "finger flu" which causes her magic to malfunction - and accidentally transfers itself to Mrs. Quick who, angered by Mr. Kraft's scheme to replace the cafeteria lady with indentured students, turns him into a chimpanzee. Meanwhile, Sabrina tries to help Valerie gain self-confidence, but turns her into a monster of efficiency and selfishness, while Salem fakes illness to get attention and gets more than he bargained for.

After Harvey arrives to help her with a class project but they spend the day goofing off instead, Sabrina's aunt lecture her on procrastination, so she tries to whip up a recipe for magical jumping jelly beans as a quick substitute for motivation. Unfortunately, she cuts corners on the recipe and produces a giant beanstalk in the back yard. When Harvey eats one of the beans, he is whisked to the top of the beanstalk where the Wicked Witch proceeds to fatten him up for her gourmet meal of the week. Sabrina attempts to rescue him, only to find that her powers don't work atop the beanstalk; and Hilda and Zelda, going to the emergency ward in the Other Realm for help, find themselves in an interminable waiting line. So it's up to Salem to conquer his fear of heights and help save Sabrina and Harvey from winding up on a platter.

A Valentine's Day episode: lovesick Roland the Troll returns, still determined to win Sabrina's love, but now he is the Equalizer, empowered to punish Sabrina for any misuse of her magic; and finding Sabrina trying to help Valerie attract the attention of brash but apparently uninterested Ken, he uses his authority to steal Sabrina's heart and carry her off to the Other Realm. Desperate for Valentine's Day dates, Zelda and Hilda summon Cupid, only to discover that he is depressed and has lost his belief in love - until Hilda makes him laugh and is aghast to discover that he is now Mr. Kraft's rival for her reluctant affections.

Libby's group is sure to win a "battle of the bands." But rather than face the music, Sabrina whips up some bottled talent for her own team.

Sunspot activity causes molecular instability for the witches present in the moral realm: Zelda's left arm attaches itself to Hilda, who is auditioning to become part of a classical trio, and a black hole forms in their kitchen sink. Because Sabrina is half mortal, they are not sure how she will be affected. Participating in a charity drive to collect food for the homeless, Sabrina is at first relieved to experience no worse symptoms than temporary hair loss; but when she protests at Libby's conniving with Mr. Kraft to turn the drive into a competition, things take a turn for the worse: Sabrina and Libby bump into each other and exchange personalities. While Libby become sweetness and light, Sabrina becomes a teenage terror who soon rules the school and - with the connivance of Salem - begins to plot world domination. When she is arrested and brought to trial, it's up to a repentant Salem to find a way to save her.

Since neither Val's parents nor Sabrina's aunts will allow them to have a car, the two teens cook up an ingenious scheme to share the costs and responsibilities for a single vehicle. Working their timetables to fit puts an intolerable strain on their friendship, however; and when the car conks out, Sabrina gives in to Salem's suggestion and buys a car for a ridiculously low price in the Other Realm. Trouble is, this old clunker has a mind and a voice of its own, which makes hiding it from Sabrina's aunts a real problem, particularly when it keeps transporting itself to her bedroom. Meanwhile, Hilda and Zelda are distracted by their own problems: they are being audited, and discover that their trusted accountant Marty has skipped town with all of their magic.

Sabrina is chosen to read her essay on learning math to the school assembly, and at first doesn't understand why everyone else assumes that she is nervous about it; then, when stage fright finally hits, uses Salem's suggestion of a "fear removal" spell. But she hasn't heeded the warning from Franklin Delano Roosevelt (via her witches' manual), and her fear spreads contagiously through the school: Val and Mr. Kraft become paranoid, Harvey is terrified of sports injuries, Mrs. Quick becomes hysterically hypochondriacal, and Libby is horrorstruck at the thought of never winning another seasonal beauty pageant. The only solution is to banish Sabrina's externalized emotion into the Other Realm, where she must confront the forest of her subconscious fears. Meanwhile, Zelda and Hilda face another public ordeal when an overworked Zelda "snaps" from overwork just before she is due to present her scientific paper to a witchly symposium, leaving Hilda to attempt to be "the responsible one" for on

When Sabrina inadvertently complains about her Quizmaster's teaching methods to a woman who turns out to be his boss, the Witches' Council rules that he be reassigned to a new pupil, the obnoxious Ralph. Sabrina, who is in the midst of cramming for her hardest magic test to date, finds herself being taught at home by her less-than-scholarly Aunt Hilda, while Zelda substitutes for her chemistry teacher at school.

On a field trip to Disney's Animal Kingdom in Florida, Sabrina, working to pass a critical test for her witch's license, accidentally turns Libby and Valerie into zebras. But nothing will stop Libby's attempts to steal Harvey from Sabrina. Meanwhile, Hilda and Zelda visit Animal Kingdom's DinoLand U.S.A., where they magically create their own prehistoric man; Harvey ends up a tour guide on a Kilimanjaro Safaris adventure through a wildlife reserve; and Mr. Kraft thinks he's finally discovered what Sabrina's hiding.

When Sabrina plays one aunt against the other to get her way, Hilda and Zelda decide it's in Sabrina's best interest if they live in separate homes. However, the situation becomes a great deal more complicated when the witches' council rules that Sabrina must choose between her aunts.

Tricked in the Other Realm into thinking that spreading false rumors is a community service, Sabrina and new friend Dashiell start telling absurd tales out of school, unaware that their fibs will come literally true in the moral realm: that Mr. Kraft and Mrs. Quick are lovers, for instance, or that Harvey is pregnant! Meanwhile, the two storytellers start falling for each other, causing Sabrina to question the depth of her true feelings for Harvey.

Sabrina must renounce one of the two things she holds most dear in this exciting season finale. The teen's dreadful dilemma develops when she must decide whether to date Harvey or new love Dashiell. She needs advice, but her loved ones are busy celebrating Mother's Day---leaving lonely Sabrina longing for her mom's guidance. Rules prohibit the unlicensed witch from seeing her mortal mother until she's certified, so Sabrina writes her a letter instead. Unfortunately, all contact is forbidden, so the Witches' Council hands down a devastating decree: Sabrina must choose between her magic and her mom and between Harvey and Dashiell. Meanwhile, Salem's mother is also coming to visit and he hasn't told her he's spending the next hundred years as a cat.
