"Yeah, guns are actually pretty useful where Pinoko is from. And since this is the future and all, I'm pretty sure they work even better in space." Space guns didn't care about water after all. Pinoko was still pretty sure they could wreck your day.

And now Pinoko is sticking her tongue out at Lina. Clearly, this is the most reational exchange between two grown individuals ever.
