Chapter 78. Gil has had enough of this nonsense, finally throws away the doubts he's been carrying since his first appearance and becomes pure awesome. So awesome, that he instantly snaps Oz out of his Heroic BSOD.
"I decided long ago. I have always known...who I wished to protect. And yet, I was afraid of what I couldn't remember, of what might be lurking inside of me and that sapped my confidence. There was nothing more to it than that. So, I guess...there's nothing to be afraid of anymore."
- To elaborate, the guy burns his left arm off in defiance of the control that Oswald holds over him (which was concentrated in that arm), all for Oz's sake.
- He does it again in Retrace 81 when Jack tries to take advantage of Oscar's darker feelings towards Oz. He responds by angrily shouting that Oscar will never betray Oz. This also gives Oscar the chance to pull off his own moment of awesome by pinning down Jack!Oz to a wall and stating that he won't let him take advantage of his feelings.
