I watched this episode on YouTube; and while it was obvious the translations weren’t 100% accurate, it was mentioned that Gengar was possibly annoyed because it was left behind. If correct, that’s very ironic knowing the writers are both aware and at fault (and will most likely do nothing to change that). Can anyone confirm?
Also, Chloe’s Eevee really is just the cutest.
Can't confirm, but wouldn't doubt it, with what we've
seen from Farfetch'd, and more recently Scyther in the last episode.
