You could have revived Aerie in SoA, but not by going to suldanesselar. I'm not sure off hand how to do it.

Also, you can exit Suldanesselar regardless of the fact that Irenicus' is mere hours away from taking the power of the tree of life yadda yadda yadda. He will wait. So, if you have a savegame early enough you can go back and finish the romance.

There would be a ToB romance if you had finished the SoA part of the romance in time.
