[ A century from now, Astarion will have already made so many more enemies. The hag will barely register for Iorveth, surely. He'll be too busy trying to keep people from actively killing Astarion to seek retribution for someone making Astarion cry a hundred years ago.

But Iorveth says 'I still wish to kill her' and not 'I'm going to kill her', which is good enough for Astarion right now. As long as Iorveth doesn't enter a portal to Athkatla, he can keep staying Iorveth's revenge until the hag is only a distant memory.

Something that he can't put off forever, though: ]

Darling. [ Gently scolding. ] I adore your teeth, [ probably too much, ] but perhaps it's for the best that you keep them to yourself if you're planning on following that old coot's orders.

[ If you're planning on following them. Because, well, Astarion doesn't care. Again, he's never heard of delayed gratification in his life. ]
