It would be interesting to see. Not just for more Vidalia, but see how Amethyst and Greg handle things too, since they're super besties at this point. Her pregnancy and Sour Cream's birth could even be what helps Greg (and maybe Rose) get some thoughts on kids.

Might even have Marty coming back, as it's implied that he and Vidalia did meet up again afterwards.

Oh god what if the new Steven Bomb this September has an episode touching this? Too deep 4 me … and I will still watch it with my heart open for the beating.
