^ Ya, still early in the relationship, too as they just did it for the first time - hope to see a lot more good romantic development between MC & Tris. RC is doing a great job with this.
It's all about pacing with these types of relationships. Do 'em too quick and they jump the shark very fast and are a huge let-down. Let them develop at the right pace with some hurdles in the process where it takes some time and the milestones hit harder and stick with you afterward where you want to replay the game down the road.
I think I'm most curious to see if RC does a bro / sis relationship in a future game where there is a much bigger cast of characters - in NMM he is limited with reactionary scenes because the cast is so small, but in a bigger game world imagine what that might look like - think a game as big as "Being A DIK" or "Summer's Gone" where the MC and the sister would be around so many people, potentially at a school setting, work, home, around friends, etc. and trying to navigate that - there would be constant hurdles to deal with which can create a truckload of drama and entertainment, not to mention hot situations once things start developing.
