I think the Justified writers have the requisite stones to go through with the death. If it's a fakeout, I'll be annoyed, although I do enjoy her as a (living) character.
KvP—I can see why you might say that, but I think Boyd's arc actually makes a lot of sense. He tries to redeem himself, but he's a career criminal (along with the rest of his family). And not only is he REALLY FUCKING GOOD at being a criminal, but even when he does try to give honest work an honest shot, his shady past follows him around (no one trusts him still, and also see: everything about annoying mine-dude).
It's hard to escape what you are, even if you want to change.
