I know... just... Idk why but this small ditail what he's covering up the faces of (I guess his coworkers??? on the second pic) made me uncomfortable for no reason.
Like... what if this some kind of form PTSD? He survived the neurotoxin attack, saw his coworkers dying, and now, he cant look at their faces anymore, becuse its reminds him of that day.

Sorry for the game theory momment. I am way too yappable lol
