[This is just so weird for Peridot to get her head around? Like. Lambert being some kind of threatening, frightening murder machine just doesn't feel right when, for a long while, she knew him as a librarian. She has such a skewed perception of this poor man.]

Um. [is that incredulity in her voice? Yes. Yes it is. This is the tone of someone who has learned something unsavory about someone they like, and is trying really hard not to say anything offensive about it.] IIII thought humans were generally averse to the idea of killing one another, so... I guess that makes that description make a lot more sense, in that case.

[You didn't specify exactly what it was that you're good at killing, Lambert, and that's on you.]
