Sam is, beyond a shadow of a doubt, not an advocate for killing things just for the sake of killing. There have been so-called monsters in his past that have been anything other than that, just trying to make lives for themselves without hurting anyone. ( Benny had been one of them, even though he hadn't thought so initially, and it still makes him cringe to think of what he'd put himself up for just to help them out. )

But, when there's a need for something - in this case, bullets for the gun that he carries around instinctively and has yet to find a real need for, aside from the familiar sort of comfort offered by its weight in his hand - exceptions are made, and thus he finds himself in the caves with Amos, always more willing to do something like this with someone else than going it alone. He watches as the jabberjay flies ahead of them, gun already in hand, ready for anything.

"Did I miss when you took up bird-wrangling?" Sam. ( It's legit, though, because he swears the other hadn't always had that thing with him, and he's poking around in his memories to try to find one in which it had been there. He comes up empty-handed. He definitely missed something.
