Betrayal doesn't require swearing allegiance, it requires trust. I might be wrong but from what you wrote before, it sounds like you allowed the Emperor to suck out Orpheus's brain while being on the rebellion path with Lae'zel in which she along with Voss and the rebels wants to free her people from Vlaakith, and for which they deem Orpheus necessary. They trust that you free him and if don't but side with the Emperor instead, they are understandably upset. Poor Voss tried to free his friend and prince for how many centuries? I forgot but it was a long term project.

Yeah... He's literally the only companion that hasn't got a messed up love life. Things are are a little complicated with Mizora and his contract, but he's just your average bachelor. Hence him hitting on Shadowheart and Lae'zel constantly in Act 1.

He can join the conversation again when they all discuss their parents.
