I had supposed either Anguirel or Feanor to pick up Aeron; natural thieves, those two.
But maybe it's best just to gently let him go..... however, what does that do to Gwyllion? So no. We need somebody to play Aeron because there's destiny there, a real mix of angst and fate, rebellion and need to find himself and his purpose. Not to mention the grief and stangeness of her ghost hanging around him all the time......
