It's too bad you can only get that scene in such a specific way. That has to be a bug, surely. I always play female characters, so I wonder if that scene would still play, given they're same sex couple.
I wish there was a scene of the githyanki egg hatching (if you took it) with SH and MC having big smiles on their faces. It really feels like wasted potential. But then again, I could say that of a lot things in this game tbh lol
