This is Sniper’s right thumb I’ve seen in various sfm photos. Did he hurt his thumb or something? His thumbnail is all black but the rest of his fingers/nails are fine looking.
His sniper rifle has a manually operated bolt action on the right-hand side. The bruise (a subungual haematoma) is caused by trying to reload too fast (too many people wanting him dead on the battlefield?) and getting his thumb caught in the sliding mechanism.
today we had a lock down drill and one kid in my class said “these are so stupid if someone really wanted to kill us they would pull the fire alarm so we would all leave the building in a big crowd and then they could just shoot us all” not sure if he is very smart or very dangerous
