Butch is not grabbing the bags because Adler told him to--no, he’s doing it because the bags are now full, and the police are coming, and they need to get out of there. So he nudges the safe closed and slings the bags over his shoulder, just in time to see Adler--

“You do that, you’ll regret it,” he says, quietly enough that only Adler can hear him, but in a tone that isn’t about to take any arguing. “Either in the hereafter, or here with me.”

This isn’t good. They need to get out, away from here. He glances to the poor injured man, hoping he’ll be okay.
