I say he has right to be selfish when he faces life in prison at best and execution at worst. But i do agree him saying it's for the good of the kingdom felt fake. He doesn't strike me as that selfless.
Eh? I, honestly, don't think so. Or at least not in such an outrageous and bitchy way like he is. If he really loves Lyall, he probably should think about his safety and well-being first, and his own second. I mean, didn't it occur to him that by defending Richter Lyall is putting himself in danger? (Now that I mention it, that's kinda funny, actually. Usually, I complain about how in furry visual novels protagonists' husbandos don't do enough for them, while here it's quite the opposite...) Anyway, he has quite a job to do to make up for his behaviour at this point.
