Whatever happened to Grubber after the events of the MLP Movie?

I am aware of course that there’s a book about him called “The Great Princess Caper”, but...I don’t consider it officially canon because it seemed to lack the magic that made the MLP fan base, particularly because of the way the story played out, and because everything seemed to be too short & obvious.

He seemed to have also just...disappeared after the last scene he was featured in.

Likely Guess is that he could be with Tempest.

Sticking with Tempest does seem likely - they have a bit of a "Twilight and Spike" vibe to them. But it's also not impossible he'd go his own way.

So I guess the questions are: do you have any interest in Tempest Shadow, and if so, what do you think she's up to nowadays?
