With all due respect, Tavi: Why should Mariah's approach to talking about her coaching change (or training plans) be dictated by the people who are speculating about it (same with Jason)? She really doesn't owe anyone, except those directly affected (coaches, off-ice trainers, parents, etc.), an explanation about her plans.
And I agree with icecoverage comment elsewhere that if TSL was going to reveal that kind of information it has to be attributed to somebody. Not necessarily a name, but simply at least WHERE they got it from. Even "sources close to Mariah/Raf/whatever" would have been OK.
Maybe she simply wants to share moments from her road trip with her friends and family and there's no other ulterior motive. I know that social media has enabled fans more access to a skater, but the skater still can decide how much (or how little) to reveal.
And since this is a fan fest thread. Whatever she's doing, I hope she has a great season.
