It is very easy to forget - or ignore - how other people change around him, all the tie. Because Sarge doesn't, on purpose, and he never will. It's hard to understand for some, especially people like Lori, who was convinced that all he needed was some persuasion. And when the sweet talk didn't work and the screaming got her nowhere she had to give up her ideas of the bad boy turned husband, the kind of guy that brings home flowers all the time and talks about his feelings. He was very close to chopping off his own head.
And that's what he was thinking about mere seconds before Addie asks him and he stills, goes completely rigid for a moment because his mind is busy trying to come up with something. Something believable, that she doesn't spot as an outright lie. Which means he is stuck with omitting most of what happens. He tries his luck with a slight shrug of his shoulders, casual, not too much. A little grunt around the cigarette in the corner of his mouth. "Ain't really cut for the regular life. Could've taken me for a fuckin' zombie if he had come any later." Which is a very interesting way of describing his engagement, really. Sarge flinches when his brain tries to conjure up possible scenarios after his rather sudden departure from Montgomery, and none of them are pretty. He picks at the bracelets around his wrist, a mixture of old ones held together by safety pins and some loose thread, others brand new and obviously made by hands not yet all that skilled. Maybe he should change topics now, but doesn't know what to say instead. Most of his life revolves around Rodeo and the Hellhounds, both touchy subjects, and he doubts she wants to hear about the camp bitches or any raids.
