Merle was one of your closest friends,you two just understood each other because you were both troubled people.

you had a problem,whenever you looked in the mirror you felt horribly fat,even if in reality you were totally okay,nobody cared for you weight, only you did.

Merle caught you throwing up in the toilet a few times already but he never said something about it.

but after the prison you lost everyone,it was only you and him and you started fighting out of nowhere and Merle snapped.

"at least I don't throw up in the bathroom looking for attention!"
