No, I don't think so. Thanks to a helpful suggestion above I managed to bypass the problem by going into town and finding her that way, so it seems that the trigger is broken. When I trigger that piece of conversation from the at-the-castle chat menu, the game crashes. But when I loaded it up from the in-town menu it appropriately loaded up the next steps.
Thank you! I'm not using any mods, but I went into town and found her in her house and it worked. I really appreciate your help.
Thank you for the response.
Lol... that was it :p I feel stupid. Thank you very much for your help, and to everyone else who chimed in!
In the clans tab, he appears under 'Members' as a companion. But in the 'Parties' tab he's not listed.
