Given her nice-sweet personality of yore, I would expect Marrina would have some level of appreciation that Namor stopped her before she hurt anyone else.
Aurora's MPD was a classic part of the character. I would like to see it the way Byrne handled it, that she remains in one persona for an extended period of time, and when she changes, she stays changed for a time...like working with two characters who will never be seen together. That said, less of the personas at war would be OK by me.
