Billy doesn't look up from where he's snapping the gore off of his blade. The only problem he's having on the outside is there's no sheath or anything to carry this thing. On the inside, he's realizing that watching Tommy fight was...

No. Don't think like that.

But he could be like that here.

Despite all the blood and gore decorating him, there's a shy glance towards Tommy, then away, before it hardens when he looks back the second time. "I've been inside long enough. Had people talking me through a nasty... what'd they call it? PTSD or some shit? Practically beat the shit out of Rogers because I didn't know what was happening. But I'm not going to fucking hide anymore when I can help. I can't help like you can or others with fucking freaky powers, but I've got an axe and I know what to hit with it. So no. I'm not going to go back inside, Shepherd."
