Warning! Massive Act 3 spoilers ahead.

Ok, so I'm in Act 3 and Vlaakith just appeared to me. The entire run, I've been playing as a loyal Githyanki to her. Vos is dead, Tav and Lae'zel do not trust Orpheus.

What I would like to do, but I'm not sure if the game will allow it:

- Lae'zel agrees to kill Orpheus
- The Emperor kills Orpheus (Lae'zel is ok with it)
- I kill the Emperor after the final battle

Is this possible? The most important question for me is whether Orpheus can die, but not at Lae'zel's hands, and she's still ok with it.
