"You'll hav'ta teach me sometime," he remarked. "M'no good at that stealth stuff. Hassled 'bout it all the time back home," he gestured over his shoulder at nothing, realized he'd gestured over his shoulder at nothing, felt a momentary pang of sadness and cleared his throat, sheathing his gun and trying to think about something else. Like having a conversation. He wasn't exactly stellar at that though.
"Tin... foil," he repeated, a crease forming in his brow before he shook his head, trying not to spend too much time thinking about something that he likely wasn't going to be able to suss out from just that word. "Reckon there ain't much y'can do to keep River outta yer head," he said with a shrug. "She don't do it on purpose, and from wh'I c'n tell she don't get the whole story. 'Least not any way she understands it. Just a jumble of thoughts and feelings and things," he shrugged again. He didn't much like that he was an open book for the girl to read, but so long as she kept her thoughts and his thoughts and everyone else's thoughts to herself, he didn't mind so much. "Reckon you could try to keep your mind clear, though. See iffit helps."
Though, thinking about that, he thought it wouldn't much. River could read deeper than surface thoughts anyway. It was why she'd gotten into so much trouble in the first place. But he supposed it would probably be better to not tell Jaime that.
