12. Bad Eggs

Complete story — includes the ending

Buffy rescues a woman from a vampire, Lyle, who escapes. At health class, the teacher, Mr. Whitmore, assigns everybody an egg to look after. Buffy's egg hatches at night, inserting a tendril into Buffy's ear while she is asleep. Buffy wakes up, ill, but the egg is back to normal. The following night, Mr. Whitmore attacks a security guard who has found a large hole in the basement. Buffy's egg hatches soon after, revealing a creature that attempts to attach itself to Buffy. Buffy kills the creature and takes it to school to study. Willow and Cordelia, under the creatures' control, knock Buffy and Xander unconscious and go the basement, joined by several students. Giles places a creature on Joyce's back and they too go to the basement, digging up the floor to reveal the mother creature. Buffy and Xander follow another possessed student to the basement. Lyle and his brother Tector attack Buffy, and all three fight the possessed students. The mother creature swallows Tector and Buffy, but, while inside the creature, she kills it, freeing everybody from possession. Lyle flees. The incident is covered up as a gas leak.
