So you are upset that Lae'Zel, who is a Githyanki, leaves the party and attacks you when you betray Orpheus and side with a mindflayer, the sworn enemy of her people? ...... Wow
So basically you're saying that if someone saves my life, I owe him nothing and have the moral right to side with anyone who wants to destroy him — just because it's in my girlfriend's interest? That is dishonorable. I live by honor. I can't turn against someone who saved my life, no matter who they are. That's why I can't betray the Emperor — it feels repulsive to my core.
You chose back in Act 1 and 2 to pursue the Orpheus Rebel path. You knew that Orpheus was the only way for her people to overthrow Vlaakith and achieve freedom. Yet at the critical moment you sided with the mindflayer? And you expected that she'd be cool with that?
I never swore loyalty to them — I only expressed a willingness to help in the fight against Vlaakith. That never included a promise to sacrifice my allies in the process.
Now true love would be you becoming a mindflayer so that Orpheus would live to free his people and that Lae'Zel would choose to stay with you
There's no love in this — just obsession and servitude to Lae'zel.
