I've recently come across this scene while checking vids on YT. All comments said this happens when she stays loyal to Vlaakith.
If you want to get a happy ending with her, she has to be shown Vlaakith's mind during her visit in act 3 (after succeeding an arcana check), be persuaded to spurn her, or not be stopped if she decided to denounce her on her own after witnessing the events at the créche and allying with Voss.
Well. Oof. Not even room for a literal cleric of Vlaakith in her life. Even knowing what Vlaakith is and does from previous playthroughs I'm a little dissappointed it ends so abruptly.
I think the idea isn't that she has to choose between Vlaakith and Tav one day so much as it's she can't focus on her duty to Vlaakith while she feels a daily duty to Tav as well.
To me, Lae'zel's loyalty feels complete. There's no room for more than one. She's all in. It's what I find most intriguing and admirable about her.
That's... beautifully put. And I hate it. I understand it, but I hate it. xD
BRB, heading to Sharess' Caress to drown my sorrows...
...between the thighs of some drow twins now that Lae'zel can't object anymore.
