Opal appeared in Journeys and was not involved in the PWC and world travelling isn't an excuse to not show off every character from the new gamesIt's just not fitting for a world traveling saga. It's too centric to one region. I'm instead expecting the PWC to come back.
Could maybe be Serena's and Kiawe's?
Nothing to say it couldn't be
Oh, so Kiawe charmed Serena with his abs? Someone on this forum is going to lose it.
Well, Kiawe's eye color is never shown, he wears sandals, and Roy's pink highlight hair is close to Kiawe's red, so it's not farfetched that Roy could be his son.
Serena on the other hand, nah.
