I played as a female human noble warrior and I decided to rebuild the Grey Warden with Alistair. I'm curious, if in Awakening, is my warden married to Alistair? I don't mind spoiler tho.
You can't romance anyone in Awakening but I had a male warden romancing Morrigan in Origins and it was briefly mentioned in conversations so I guess you'll get some dialogues specific to Allistair in your playthrough.
