+1 totally agree. I think changing the order of events in the scene is a bit difficult, it’s not like the sun can wait to burn Astarion until he persuaded Karlach to live. But I think there has to be some solution. Like having the conversation sometime before end game, similar to how we can push gale towards or away from the crown, we could push Karlach towards or away from returning to Avernus. Especially if Wyll became the blade of Avernus, they should go together, there is no reason why Wyll would not try to persuade Karlach on his own, especially because he already suggests it by himself if you play Tav.
