As much as I'd love to see Tessa and Scott this season, Tessa'a health and future ablity to actually be able to walk and move w/out pain for the rest of her life is far more important. If they have to sit out, then they have to sit out.
As for the "D&W will win Worlds w/out V&M being there" talk, I remember Kurt Browning's late Father saying something along the lines of how the ice was always slippery side up. I do love D&W, but have not been wowed by their FD as of yet this season and that's a disappointment as I was really looking forward to it too. We'll see what US Nats show and I really do hope it shows growth, but it's starting to get awfully late in the game to start overhauling it.
I don't think it's a slam dunk for Meryl and Charlie at all come time for Worlds. Would really love to see them win, as I am a fan, but I'm also a worried fan of theirs. It just seemed that exquisite FD they had to Samson and Delilah two years ago really set them up to expand on that and show us more of that potential they still have in spades, but instead have reached some sort of plateau.
I hope they're able to get past it somehow, but am wondering if it will happen or not.
