I believe Aranvald has the blessing, or it becoming implied. These past 2 patches were in Doma so he wasn't involved, but he was pushed forward a lot in the 4.1 story.

As for a new Scion, or a new main character in general, we need a male miqo'te, that is the only gender/race that hasn't been a main character yet. All of the others have been.
