[There is a long - noticeably long - moment where Neuvillette simply looks at Childe. It's not quite a stare, but rather almost as if he's waiting for something to happen. When nothing does (or, at least, what he seems to be waiting for doesn't) his brow twitches lightly and he straightens up.]

... I will admit, I wouldn't have expected you to greet me so casually, Mr. Tartaglia.

[Given... everything that had happened only recently, for Childe to approach him in such a friendly manner doesn't align with what he thinks he knows of the man so far. He would have expected at least a challenge.

Strange, and he can't make sense of it.]

We weren't on the best of terms when we last met.
