@Howling wolf pretty dumb isn't it? He's questioning the different scenarios happening and surprised it's different from what he knew while not realizing that his very existence triggered it all. Of course the butterfly effects already started. Guys like him is just like those retarded MC thinking that if he do something different, it wouldn't change the outcome that already happened before and if it outcome is totally different from what he's expecting, hed cry like a loser and react like what he's doing now. He should've know from the start that after regressing, all the things he knew is just reference and a potential outcome to happen not an actual outcome that set in stone no matter what he do since he already started the change.
I don't care about your taste!
