[Glancing over the survey, Crow doesn't... feel very eager to answer the questions. Things he's willing to share completely honestly with someone he barely knows (and a cop on top of that) end around the "how long you've been here" part, and while he doesn't mind talking about his world in general, the fact Spencer asks about the supernatural aspects of it makes it really difficult to respond to, if only because the duelist isn't the lying type (besides, that would make the survey useless, right?) and he doesn't want to talk about how he's involved in fights between gods here.]

... Not to clip your wings or anything, but people have been trying to figure that out for years, with no result. I don't think there is any pattern to be found...

[Although, to be honest, he's been noticing some things, such as his two best friends from home usually coming and going at the same time... but that no longer applies.]

As for your Pokémon, you might have better luck asking Nurse Joy... she'll probably know what to do.
