Maybe Morgana can't command Aithusa. Them teaming up could mean that Aithusa helps her deliberately. The dragons have also a free will after all. Someone else could be Aithusa's dragonlord, someone who is on Morgana's side.

I have always thought about the possibility that Morgana isn't Uther's daughter but that maybe Agravaine was her real father. I would like that because, as stated before, I don't see similarities between Uther and Morgana and it would be better for Uther's memory since he has always been held responsible for what Morgana did.

In case Vivienne had lied about that, the magic couldn't have been the reason because at that time, Uther had no problem with magic. But actually I don't believe that they are changing Morgana's paternity. My guess is that Aithusa helps Morgana due to other reasons and not because she can command him.
