Otis
 

BELOW: Otis feels terrible about shooting Carl; he points how that he is non-violent and doesn't believe in killing:

Tyreese: Otis, right?

Otis: Yeah.

Tyreese: I don't know if you caught it before. I'm Tyreese. You doing okay?

Otis: I wouldn't hurt a fly--I mean... I was out there huntin' but I wouldn't kill no animal I wasn't going to eat. I'm real gentle, I ain't violent at all. And I-- I shot that kid. I understand why that Rick fella wanted to kill me. If'n I had killed his boy... I'd a wanted him to do it... I'd a deserved it. We still don't know if he's gonna live.

Tyreese: I ain't saying what you did was right, but you can't worry yourself to death over it. What's done is done. I'm worried sick about Carl, but there's nothing you or I can do about it now.
