stevenuniverse, stevonnie >>> He left on his own, after seeing they were two kids. And is also in a later episode as well. He could simply be an opposite of Stevonnie, but even so -If he is-, Who fuses to be him? Opposites of Steven and Connie?
I still don't understand why "bumblebee" is spelled wrong. To avoid confusion because Yang's bike is also named Bumblebee, I guess? I'd just as soon call both the ship and the bike Bumblebee, but oh well.
