"Or we what?" He damned well was paying most attention to her, what with this hand slicing, and emotional back and fourth from being genuinely agitated to jumpy, almost...fearful.
What was Elizabeth afraid of? This was more than just some interpersonal issue. He could see that now. Elizabeth didn't second stop herself from speaking up or avoiding a thought when she knew damned well she could say what she wanted in front of him, Stiles or not. Only, and if only because the other boy was here, did he not push the subject further that moment.
"Right." Booker wasn't buying her teetering or hurry to cover. He only sat up in his seat, cocking open his shotgun to show the empty casing, pulling out a bullet from his vest pocket to hold out to Stiles. "Now all we gotta do is figure out how to grind 'em down, and get it in here without tampering with what this is supposed to do. Long as we keep it in the casing, and there's something to ignite the bullet, I don't think there's much in the way that silver'll hurt it from going boom."
Then again he was just the simple mind here. Simple enough to use anything to kill whatever required killing it. He'd jam those pieces of silver down the monster's throat if that's what it took. But since he had the opportunity of more elevated minds to possibly make things easier, well, he'd let them work their magic if they were so inclined.
