imagine Greg just getting used to Stevonnie. Every now and then, he leaves Steven and Connie alone in a room to get snacks and comes back to one large hungry child instead of two small ones and it’s just like “oh hey Stevonnie!”
and sometimes Stevonnie calls him “dad,” sometimes “Mr. Universe,” sometimes it gets jumbled up like “Mr. Dadiverse” or “Dadster Universe” and it’s still just casual and Stevonnie doesn’t notice and Greg still loves them the same.
I just love the Steven-Greg-Connie family dynamic and I want to see all of it
Dadster Universe
I imagine that he also understands that stevonnie is a separate being from steven and connie because fusion is more than just two people sharing a body.
