I just find Yrliet wandering like a street hobo and I'm taking in the xeno witch in again.
Holy god, I'm such a goddamn simp.
There was just a little discussion about this on the steam forum. If you're not playing Dogmatic, it's actually quite reasonable to forgive her, because she didn't actually betray you, at least not in the sense that her intention had been to hand you over to whatsisface. It's clear from the dialogue that the worst you could say is that she was blinded by her quest to find out the truth of her homeworld and naive in trusting her darkie "kin." In fact, the only person who betrayed you (or was about to) was the Inquisition guy (the one on Dargonus), who she rightfully killed. She's quite broken up and contrite about the events.
It's a shame that there's no option in the dialogue (particularly after Act 3 when the pissed off retinue ask you to eject her) such that you can clarify the truth of the situation (though it probably wouldn't make any difference to them, the consequences of her error were so horrible for everyone).
