I'm on Welkin's side on this one. You can't really expect someone who has lost someone that integral to their life to make logical, smart decisions. He is obviously killing his emotions just to stay sane, and everyone around him acts as if they want him to "cheer up" and act like he always did. That expectation in itself is unfair, and self-centered. Alicia adding to the problem by confessing is a fantastic way to top it off.

Faldio punching Welkin reminds me of a scene in Ef. No matter what excuse he makes, Faldio hit him because of his own frustration. The girl he likes likes Welkin after all. Other factors might contribute, but that would be the most relevant one.

Faldio complaining about losing his subordinates was stupid IMO. He lost comrades, but Welkin lost a comrade, and probably the closest living person in his life, who he has known and depended on since childhood, who he considered as family. I really can't see how this can compare.

I am not saying Welkin has the right to act emo forever (it isn't even emo really, since he is killing his emotions, the opposite of being emo), but he at least has that right for now, without people badgering him to act the way they want him to act.
