Yeah, when it comes to building a relationship I think we have to have them make it through this part of running away and come to rest in a situation where they'd maybe have to get disguises and hide in plain sight. This would be when they can experience 'life' and start to reveal stuff to each other. It would help to introduce a trusted NPC who can facilitate this, sort of like someone in an operator role. Since he's a musician by hobby, they would likely connect through that, and the difference in experiences also means that they can each get the other to try certain things they haven't before.
