I'm a little confused about the nature of MT. See, I was under the impression that everything in the train was really just artificial, holograms or something. And that they really just existed for the purpose of providing the passengers with challenges to help overcome their flaws.
And for the most part, that appears to very much apply, it's in line with what we see. So with all that in mind, I assumed that MT wasn't really Tulip's reflection, just another challenge of the train and that she'd still have a reflection once she got off. But appearently she is indeed her actual reflection?
