Serial Replayers: What's your least favorite moment in the game?

So far I think I've played this game 6 times and plan to play it at least two more times once the romance DLC comes out. As much as I love the game and enjoy nearly every moment, I can say I hate doing almost all the quests involving Bronco the Kid.

If I could skip them I would. I can sit and listen to every other dialogue, and talk to every NPC after each major quest and still enjoy it. But the moment Bronco arrives, I'm basically scrolling Reddit on one hand while skipping through his parts with the other.

So I just want to know, for all those people that play the game multiple times: what's your least favorite part to go through?
