It's smart not to trust Will at this point, as the man plays up his own emotional display even now, an attempt to get the best response. It's cheap, but these are the defenses he has. They're all he has that he knows can work.

So Sheehan calling out his bullshit gets a weak attempt at a smile, and a mumbled response of "perhaps one line." The 'not forgiving you' part gets a nod and a swallow.

"...thanks. I know it doesn't fix...anything, really, but. Hopefully it helps somewhere down the line. I'd like to try and still be friends at...some point, but I'm not sure..." He shakes his head. "I'll think on it. If there's anything I can do."
