Umm. Reaper did actually die, and has done numerous times. The whole point was Mercy tried to resurrect him after he died but botched it to the point where he was revived and his cells regenerated at a faster rate than they could deplete subsequently making him immortal. His despise of mercy and overwatch came from this Incident which is why he joined Talon. He even occasionally says "At least you got it right this time" upon being resurrected by mercy. Also Gerrard LaCroix is confirmed dead.
Yeah, I didn’t mean to put Reaper in there because of what you just said.
And I just wanna say, I don’t really think Gerard will be a hero. I want to know more about him and Amelie, even if it’s unlikely xD
