I just watched it; first of all, I love that programme; it's really grown on me. I'm totally bummed we won't see that at worlds. What a shame about those sloppy mistakes - and that's clearly the problem. Mirai skates like this fairly often; good but not great - and, most significantly, not up to her potential. Frank probably knows how amazing she is and could be, and is probably pissed off with her apparent inability to skate "clutch." And, if rumours are true, if she is lazy and at times difficult in training, he's probably pissed off with that too - if she could bring all that energy together at the right times and skate lights out he'd probably be more tolerant of it, but as she doesn't, and as that attitude isn't pushing her in a positive direction, he might well be sick of it. I was a bit @ his reaction in the KnC, but maybe it was a deliberate move by him. Tough love n all that.
