Not that I think there should never be new characters ever. But like, it really depends on the situation.
I can't say how this go, since I haven't read EXM yet. The story could hinge on there being three kids. But I would have gone with Bronze and cut the other two. Have her be the Kitty/Jubilee, and the other two spots could have gone to more veterans, or older students who could relate to her in ways the adults can't.
