They could reuse the old voice file for all I care. As long as we get to relive the moment and experience dem feelz, all is well!
I still kinda want to hear that song Leliana was said to have made about her travels with the Hero of Ferelden, after the Blight. With changes made if she was romanced, of course. Unless 'I Am the One' really is supposed to be that. I've headcanoned that in the past. :3
Has anyone figured yet what happens to the Leliana romance in Inquisition if you had the Warden marry Alistair in the Keep while you were still in a romance with Leliana?
Does the note change?
Is there different dialogue?
Did the Warden not go with Leliana to the Waking Sea Chantry after the Fifth Blight?
She says something along the lines of 'She married King Alistair, but it didn't matter. She loved me.' and is introduced as the mistress to the Queen of Ferelden at the ball. From what I've heard, there are no other differences besides that.
Apparently DA:I kind of assumes you hardened her in DA:O, with that scenario. She ends it if you if you marry Alistair while unhardened.
