Yes, Mearns is great in this role, so it will be disappointing if she is replaced. I'm pretty sure I saw Unity in the role, and that she was unremarkable in comparison to Mearns (and Kyra Nichols, going back in time!(. The lead role has to be danced with abandon, which is why Mearns is so good in it. I've never seen Phelan dance with abandon.
