(I'm sure she'll "order" him back or something when the town's in need of assistance, which will negate the whole thing, but for now - she's finally awesome.)
I'm confused... I was under the impression that once they crossed over, there was no magic whatsoever. So Marian crossing over took away her "illness", and Rumple crossing over... just means the dagger doesn't work on him anymore. The no-magic rule of our world negates the power of the dagger. So Belle can order all she wants, he's not doing s***.
