Henry may have shown a passing interest in a couple of girls, but he’s just a kid who hasn’t even been on a first date yet, so he could still go either way. It really could provide for an interesting storyline.
Perhaps Gepetto and Archie could get something going since they have been life long companions. Cricketto anyone?
I could totally ship Cricketto. They’ve been through a lot together and are already close, so I’d buy it if they got romantic. Think Marco may have mentioned having had a wife at some point, back in the Pilot, maybe? That was his cursed self talking though, so maybe the curse made him think he was straight to ensure he didn’t find a love that would make him happy?
