Eggy is an alien, ofc. And Ran was the person he knew, obv.
I don't think it was Ran's mom. Since it showed Ran climbing into the Eggpod as a child and both Eggy and Ran remember the indecent. (Or in Ran's case she has a drawing she made of it happening.) Also when Eggy remembered it he remembered knowing Ran's name. Something isn't adding up though.
ran's mom is eggy's childhood friend right? so both were kidnapped by those ppl from future and were left in different timezone. its too bad eggy cant meet his childhood friend anymore, but he got to take care of her only child ran
