Perhaps he should be more open to what Erwin is suggesting - he has spent more time talking to him, after all. And while he isn't going to discount Erwin's thoughts entirely (so often Erwin sees things that he doesn't, including the larger picture), Levi can't discount his own instincts when it comes to people. They've both known some fucked up individuals, but Levi has arguably spent more time around people like Kimbley. Kenny had been only one or two steps away from that point, really; he at least had had one or two people he did seem to care about.

His expression flattens, matched in his voice. "Maybe because who he is is super fucked up."

He shifts away a little from the tapping fingers - that's not a particularly welcome sensation at the moment, drumming jitteriness back into his nerves. The water is finally ready - not yet boiling, but on the cusp - and he falls silent, pouring it out with a critical eye.

Turning back to Erwin, a deeper frown creases his expression.

"And what if there's nothing to get through to? You'll have just put yourself the closest within reach of someone who can turn you into a fucking human bomb just by touching you."
