Curate, connect, and discover
I could totally imagine when Ken arrives to the Ultra's home planet it's gonna be like that awkward feeling where you go to family reunion to the side of the family you never met before. Aunts and Uncles that never heard of you before being all surprised and crowding around and the cousins who already have that bond either unintentionally excluding you and/or awkwardly carving out a space to include you in the plans. And Ken is 26, he's basically the baby too so that's a whole nother thing.
These three are totally the cousins that claim him bc they're the closest in age (and not bc I'm currently watching the series)
And he's a hybrid so everyone is going to have questions, maybe like how is the "human host" surviving or why is he so small or tall depends jk
Oh then they're totally going to fuss when they find out he has a daughter,
It's like visiting cousins from another country tbh
