Oh that's because his memories are conflicting when the others had their memories restored they had been immediately told that what they recalled is the past and that they're living in a different time line. You can see his eyes are still in the locked daze of the memories so when that settles he'll understand the differences.
;-; We're just all apprehensive on his aftermath actions when he's adjusted... sort of glad I read the spoilers for this much.
For everyone being angry at him, I think he still thinks he’s in the past? I don’t think his memories were restored correctly since he says “I thought they were all dead” or something.
