[Again with the ghosts..!! But the pokémon's appearance isn't scary, luckily. If anything it looks (and sounds) like a happy little creature. Tepig squeals cheerfully, moving around in Hijikata's arms to get closer to the new arrival. He holds it back and cautions it.]

Don't, you might get zapped.

[He just assumes that that may happen with electric-type pokémon - and in any case Rotom clearly wants to be back in the phone, disappearing (and reappearing on the hardware) as soon as it showed itself.]

Honestly, the more I learn, the more overwhelmed I feel. You and your advice will be in hot demand in the coming days.
