Just to get her off the show? Now, I realize she may appear in the future, to some extent, but she's no longer part of the core group.

Is this what they'll be doing with other underutilized characters on the show, like Zeb? I know Rebels is basically Ezra's story, but it irks me when they finally flesh out Sabine's character, then swiftly get rid of her.

We'll see what happens, but I'm thinking they are paring down the group for a reason.
