[They can compare later once he's more settled in, he already wants to see what's different between her gun and his own. Maybe design something based off it with his own flourish, or even tinker with the thing itself, if she'll let him handle it. But for now he relaxes once she's holstered the gun, and nods.]

She was very irresponsible with them, yes. [Although if Percy were to be asked, he'd rate himself as much worse, considering he invented them and then let her get away to spread them.] My hands aren't the cleanest, but I know the damage they can do, I know how to mitigate it better than she ever wanted to. [He sounds...pretty regretful, honestly.

But this woman is a stranger and Percy would much rather speak of something else other than Ripley, so he quickly moves on:] Yes. In this case it just makes the hits hurt more than they ordinarily would, but—well, you've seen what happens when it jams.

You don't have magic where you come from, then? [He sounds a bit intrigued. Magic is commonplace where Percy's from, and he even has a scrap of magic to his name, just enough to cast small illusions. A world without any is foreign to him, and therefore interesting.]
