It certainly feels like does as much harm to her characterisation to have enabled this dialogue... what if this was simply a clumsy oversight and it wasn't meant to come out yet?
Would have felt so much more better from a narrative point of view if it had rather been in the process of a rewrite for this moment in the game, so thats all I could think of in terms of compromise if its really here to stay as is.
This dialogue has been in game since launch but was flagged IMPOSSIBLE. I really hope this was just a bug with the flags as they are constantly mucking up her dialogue triggers right now. Apart from it being ooc for her this would also mean that a DUrge player would never have the chance to see her romance epilogue.
