She never told me, though I suspect it has to do with her manipulating the fabric of this pocket dimension, she always was the best of us in that area.
I do not think so as I only learned it after becoming the white tiger, guard this secret with your life, if the clinic is purely on Emma's shoulders it could change on her whim, one thought and you could be dead. Each dimension has an unclear future, it's part of life, the fact that you will have to step away at times and let things be.

These are the lessons that can only be learn through experience, and not the kind of experience that leaves kind memories, the experiences that leave you wishing you could have done anything but nothing. Watching civilization after civilization die and wither away, one nudge little nudge centuries ago and they would have lived forever, forever to enslave the rest of reality.
