Mark

Mark is a tall, slightly chubby Chinese male who appears in Chaotic Rooms.

Chaotic Rooms
Almost immediately after Claire meets Mark in the Dyson Sphere Storage Facility, Gabe stabs him in the neck and Claire leaves them behind in the warped room. Mark opens a door that floods the warped room with water and Mark escapes with the pocketknife only to encounter a room full of bowling balls. Mark ends up falling into the room below and dying in front of Jack, escaping the storage facility.
