[It's much easier to do when he's happy and not angry :D]

[He is also perfectly happy to explain the situation to her directly without being infuriatingly roundabout like he is with every other newbie ever. Unserious mission briefing let's go.] Well, we've been dragged into this other world called Johto, no one knows how or why. And nobody can find a way to go back home willingly. Hell, I've been here almost a year. But sometimes people vanish and everyone assumes they've gone home. We're all given a Pokemon to train and fight with, and as far as I've been able to tell it's just the local sport and a way to fend off the wild ones. There's not much else to do. And you're lucky you didn't post that question to the network or you would've gotten fifteen people telling you all that over and over trying to be helpful.

Oh, and we've all been turned into humans, I'm sure you're happy about that. [He's definitely not and it shows in his voice, but since he thinks she's the Lust he knows, he assumes she's thrilled because it's half of all she ever talks about.]
