Buffy and her mom are at the mall shopping and Buffy is given the charge of picking up an outfit for Joyce. As Buffy sets to the challenge, she notices a vamp with a girl. She follows them into the closed game room, where they are playing pinball. He is about to bite her, but Buffy stops him. He's super country: southern drawl and cowboy hat. They fight, but he runs out.
Cordy and Xander make out in a janitors closet and they continue to banter. But, once again, they kiss.
Xander, Cordy, and Willow are in family living class and they are assigned "children"... eggs. Buffy skipped the class, so she is designated the single mother. She is wigged by it... doomed to be a single mother. Meanwhile, Giles figures out who the mall vamp was. Southern dude has a brother.
Buffy and Angel do the patrol thing, but all they end up doing is making out. As they continually make out, the Gorch brothers watch.
Buffy goes home and puts her egg to sleep. As she is sleeping, a series of tentacles emerge from the egg. They cover Buffy's face as she sleeps. Then, in the morning, all is normal once more.
Buffy gets to the library and she and Willow are completely wiped out. Xander on the other hand, boiled his. Xander displays stupidity and Cordy walks in and proclaims that the family living teacher is missing. She throws subtle hints to how she would like to look in some.. closets. Buffy plans to sweep the cemetary.
Ah, and so they make out some more. The subject of parenthood comes up. Angel says he can't have kids. Very sentimental. They kiss some more.
Meanwhile, at school, the janitor looks in the basement and finds some mysterious activity. Just as he is investigating, he is knocked up side the head with a shovel thingy by the family living teacher.
Buffy arrives home just in time for her egg to hatch. The creepy tentacles are part of a full blown tarantula like thing. She picks up an iron and looks for it. At the last moment, she kills it. Completely freaked out, she calls Willow and asks her if she had a similar problem. She says no (although it can be seen that the egg has hatched). Buffy hangs up. Then her mom comes in and asks her what is wrong, and of course notices that Buffy is in her street clothes. Buffy is put on probation.
At school, Buffy asks Cordy if her egg is screwy. Cordy says no. Willow comes up to her. And, in the distance, Xander decides to eat his young. And (major eww), he nearly eats it. It is reveled that Willow has one attached to her back. They set out to dissect. Willow says that he said to get started. Buffy and Xander begin arguing about who should dissect it. Willow starts talking about a mother bezoar and Cordy knocks out Buffy. Then Willow knocks out Xander. They drag them into a closet. Then a whole bunch of students head into the basement with hatchets.
Buffy's mom arrives at the library looking for her. All she finds is Giles. He acts slightly strange and then puts a creepy crawly on Joyce's back. They join the brigade of psychos.
Xander and Buffy come to in the closet and find that they are accompanied by two eggs. Buffy smashes them and crashes the door open. They rush to the library and Giles isn't there. They look up bezoar in a book and figure out that Giles is under the creepy spell. All of a sudden, they hear a commotion in the hall. They go out and see Jonathan. But, he recovers and says he's fine. He starts walking toward the basement.
Buffy and Xander follow him and find most of the school including Willow, Cordelia, Giles, and Joyce harvesting eggs from a mother bezoar thingy. They go inside and pretend to be one of the gang. Xander follows Cordy and Buffy goes in search of a weapon.
And it is at that moment that the Gorges decide to attack Buffy. They fall into the room and it becomes all the psychos against Buffy & the Gorges and the Gorges against Buffy simultaneously. Cordy attacks Xander, and he punches her out. Then, one of the brothers is killed by the mother bezoar. Buffy falls and is caught by the mother bezoar. It drags her in, but she takes a hatchet with her and kills it. All the little creepies fall away from everyone and they faint.
When it is all over, no one really understands what has happened. But, they are all told it is a gas leak. Of course Buffy's mom doesn't get it. And, yet, her mom still rags on her about not being in the library. Her mother confines her to her room.
Buffy finds a way around that rule. Angel comes to her window and she stays in her room while they kiss and he's on the other side. Way sweet.
