Gordon and cam would have been obvious and boring. But not showing any sign of recognizing the most attractive girl in the world is asking him to save the princess with him - Liberace would have been conflicted.

You're probably right.  Still, those episodes might only cover a day or less.  Especially now that they're leading up to the climax.  Also, the governor is oddly missing from the preview for next week's show.

Anybody else suspect the governor maybe got bit, based on the way he was holding his arm and his weird jovial manner at the end of the episode, and we never actually saw him escape when his situation seemed pretty dire?

You're missing the point that Gran said that, due to the alzheimers, she "didn't think" she'd sent the invitations.  Obviously she had, but she didn't remember.
