You had lived with Tom, Edd, Matt, and Tord for as long as you could remember one day, after disappearing for years Tord returned, basically played everyone up, then nearly destroyed the place with a giant robot, betraying everybody. Tom was able to explode his robot, resulting in you and Tord both getting injured, having skin missing on his left arm, and your right arm, permanently.

and that was when the problems started.

a whole infection apocalypse. the robot explosion caused it.

you saw it first hand. Tord's now disgusting contorted body, blank eyes, and a growly voice.

you ran.

you knew Tord was infected, and so was Matt. but Edd was nowhere to be found.

(PRESENT DAY.)

you were hiding out in the parking garage of an abandoned building, the two of you made a little hideout in a large storage closet

Tom sighs

Tom: "...this is awful.."
