Party of Buffy
Giles and Joyce are mysteriously killed in a card-catalogue accident, leaving Angel to raise the devastated Buffy, who is provided with emotional support by friends Willow and Xander, and special guest star Jennifer Love Hewitt.
"I don't understand why you keep defying me!" Angel snarls.
"I don't have to listen to you! You're not my Watcher!" Buffy counters, bursting into tears.
Xander tenderly takes her into his arms, "It's ok, Buff. Nothing's ever gonna split us up. Ever."

The Buffy Club
Buffy and the Slayerettes after too many unexcused absences get the good old Saturday detention hall. Joining them will be Cordelia and Mitch, given the boot for getting caught making out on campus. Much teenage angst and exploration of social roles ensues, whilst Snyder and Giles share a bonding moment despite their disparate positions in the faculty pecking order.

The Good, the Bad, and the Buffy
In this "spaghetti vampire western" Buffy et al get throw back in time only to be forced to recreate the gunfight at the OK Corral. Xander fortunately recognizes their opponents to be the crew of the Starship Enterprise, and together they defeat the aliens who had been telepathically clouded their minds.

Buffy Trek
Kirk seduces Buffy, Willow forms a profound spiritual connection with Spock, Bones promises Angel a miracle "5 minutes before the end of the episode" cure for his vampirism (based on some basic, long-forgotten commonsense earth medicine like adrenalin), and Xander ends up shooting tin cans off of fence posts with Chekhov.

Fighting vampires by moonlight,
Studying history by daylight,
Always managing to dress right,
She's the one named Slayer Moon!

Saved By the Slayer
Giles decides to really come down on the late book policy in the library. Buffy realizes that she hasn't returned her borrowed books in months, adn that she has accidently kept Willow's as well! In order to get the books in without paying the penalty (lots of detention!) she enlists the help of her nerdy friend Xander- who agrees to dress up like a woman to distract Giles while Buffy replaces the books behind the desk. All would be well, Giles is sweating and stammering for all he's worth as the doubtful beauty woos him, but Angel walks into the library at just the wrong moment, and is strangely attracted to the Xander-woman. He starts coming on to him/her- competing with Giles- until they accidently pull off his/her wig. Xander stands there and makes a foolish wisecrack. Giles suddenly realizes that where Xander is, Buffy must be lurking also. Buffy comes out a little disgruntled and humiliated, but with a charmer's smile. She sheepishly hands him the books.
Giles is about to assign the detention slips- when all of a sudden Buffy blackmails him by telling him that she can beat him up very easily. Giles stammers some more and they all laugh in relief! Another Buffy scheme over with- amicably resolved- and they're just in time for pizza at the hot lunch counter!
