So trying to understand why in the world they can't recast Kate with a new actress. This is done all the time, and certainly in other super hero movies or shows - Rhodey recast with Cheadle in the Marvel movies.
So it seems insane that the CW is doing this. And it looks like they are from the stuff I look at, but maybe I'll be surprised.
For sure, if Kate/character was absent or totally changed as being suggested, I would have NO interest in watching the show.
I've enjoyed Mary and her path and would not mind if she became a version of Flamebird, since the personality is close.
But I have to have the blonde hair, even if it is an obvious wig.
