Synopsis[]

The team returns home with unexpected cargo. An unsettling experiment occurs, and a new talent is discovered.

Plot[]

On the Maginot, Nibs asks Curly why the hybrids were all named after Peter Pan characters, and why Marcy gets to be Wendy. Boy Kavalier orders Kirsh to collect the creatures and bring them back to the island for study, despite objections from Kirsh and Dame Sylvia. Morrow finds Smee and Slightly guarding the Xenomorph eggs and interrogates them, suspicious of their childlike behavior. He flees shortly after Kirsh arrives when an egg begins to open. Meanwhile, Wendy finds Hermit captured by a Xenomorph. Wendy kills the Xenomorph by decapitating it, but both Wendy and Hermit are seriously injured in the struggle. They all return to the island, where Hermit undergoes surgery and Dame and Arthur Sylvia tend to an unconscious Wendy. Boy Kavalier inspects the creatures until Kirsh removes him when he gets too close to a Xenomorph egg. Later, Atom Eins questions Smee and Slightly about their encounter with Morrow while Boy Kavalier secretly observes them. Somewhere in New Siam, Morrow calls Yutani. She orders him to return home, but he refuses and insists on retrieving the creatures himself. Back on the island, Curly asks Boy Kavalier to explain why Wendy is his favorite of the hybrids, and Curly insists that she is the best. Morrow contacts Slightly by unknown means, frightening him, but Morrow convinces Slightly to be his friend. While Kirsh, Tootles, and Curly dissect a facehugger and introduce its larvae to a sheep's lung, Wendy awakes hearing loud trilling noises that cause her pain. Wendy sets out to find the source, ending up at the room holding the Xenomorph eggs before collapsing on the floor.
