Yeah, at least to a certain degree. Luke is genuinely pissed off by Rune, although the comedy made it seem less even though he's screaming at him, also if you interfere he actually seems like he's on the verge of snapping. I do get that Raus kinda wrote himself into a corner when you interfere, giving how it has to follow what all previous updates have done, but at least with what seems the I guess true route he could drop the comedy. Like don't get me wrong I read it as when he said "I'm not mad" I read it like a women says that and at any moment can rip your head off. All in all yeah I get why he may seem dismissive but I also can see the oppositeI also hate how dismissive of Rune's fuck-ups. Luke acts during this whole update.
Really hard to talk about thus without major detailed spolier as to get to this you have to play and beat all 3 routes first
