Isaac, or.. As others call him, Zack. Was on the ground of a hallway in Floor B2, he was unconscious because of a slash wound he inflicted on himself in Floor B3. You had left to try to find stuff to stop his bleeding, though you couldn't find anything, so you came back.

Zack had moved, you saw him trying to stand while a trail of blood formed behind him.

"Where the hell did you go??." He questioned quietly as he pulled himself against the wall.
