The more stuff I read that Sena wrote and see how she behaves, the more I can't understand why anyone would hire that person. Or worse, work together with her for an extended period of time.

From the stuff she says, she seems to have a very poor character, and toxic is really just the right word to describe her. Of course, the fact that her VA work and delivery just were plainly bad in DT makes the whole thing even more frustrating.
I don't have any hope they will recast Wuks VA...but they certainly would not be in the wrong to do it.
