I love the idea that the Eridians briefly think that Rocky Came Back Wrong.
He shrugs and nods and does weird shake things with his carapce and their just like.... bro, why are you moving like that? He also talks so fucking slow and enunciates like his beautiful family is 20 years old. But when Grace is done being scurvy and rickets ridden and is capable of joining the thrum outside his earth enclosure, they realize Rocky spent a few years talking to a slow as fuck human incapable of converting to Eridian seconds in his head. He's pausing to congugate and he frequently needs words above a 1st grade level defined to him.
Damn, our planet was saved by a 30 year old? The planet fucking sent a CHILD into space? Rocky spent the entire time in space babysitting. You need to sleep. You need to eat. Damn, build him a statue he's now the patron saint of children.
