Would have Javi and Luke liked each other, maybe even become friends or would it be similar to Kenny as well?

They're generally both pretty kind-hearted and put a lot of stock in family, I'd say they'd be pretty fast friends

Unless you're doing a scumbag Javi playthrough

I think they would have got along pretty easily. I'm pretty sure Luke would be the type to gush and fanboy secretly after realising Javi was a baseball star hahaha

i think they would’ve gotten along well. if you want another Kenny situation then bring in David lol
