"I’ll weep, wondering what happened to my mad love." Astarion x Dark Urge romance

If you play Dark Urge, eventually, in late Act 3, Tav gets to try to get rid of the urges for good or embrace them further. There is a possible outcome where neither of these happen: instead, Tav becomes an outcast cursed to be a murder beast forever, never to be able to get rid of the hunger. This is non-Ascended Astarion’s reaction to it right after the encounter. How to trigger this dialogue: First of all, make this happen post-Cazador and have Astarion not complete the ritual. Then, when you are in the temple, accept to duel Orin fairly, do not have other companions intervene. If you lose this duel, it triggers a cutscene where the butler calls for the remaining companions to avenge you. When you win that fight, Bhaal resurrects you only to say you are a disappointment and a failed Chosen but also doesn’t take the urges away.
