Hayden have other stuff, but they are in the talk screen (Where you pick the topic you want to talk). He have to like you enough and I think for now it's only for bottom males.
Scenes you mean the artwork scenes? Bandit one is before you have a fight with Scar, there's a chance for an even to occur during sneaking into the camp. The one with Wererat have a chance to appear when you are in the bar's basement. The one with Logan and Fat Bandit is when you encouraged lumberjack to go visit the bandit's camp and are finished with the bandit side story, then you can see that scene during the night when visiting sawmill.
