Apocalypse Au

Jeremy, Brooke, and Chloe are infected.

Michael, Rich, Jake, Christine, and Jenna are a group of survivors. ((They have weapons and shit))

Scenario(Boyf riends):
The group of survivors were resting for a night at an abandoned camp. Michael volunteered to watch for the night, so everyone else went to rest. Late at night, the group was woken by the sudden clashing of objects from outside, and quickly went to investigate. They saw Michael holding up his gun, but not firing. He had his gun aimed at a single zombie, that wasn't trying to attack him.
"Michael, what are you doing? Kill it!" Jake said. The zombie didn't look away from Michael, and Michael didn't look away from it. "I c-an't..i-it's J-J-Jeremy." ((What happens next?))
