The access to modern conveniences would be amazing for him when he realises they're up-for-grabs. Things like modern cooking ranges alone would be things he'd never even considered could be out there, but he'll have to figure out where and how he can actually buy them before he can stock the homefront.

On the gym side of things, while Lucius isn't particularly interested in fighting in them he's still a Roman through-and-through. Watching arena combat, whether with Pokémon or gladiators, is something he'd be more than happy to take part in. So once they get to know one another he'd be happy to be Geddoe'e cheerleader xD
