From the perspective of ice dance politics, V/M ended this season in a very weird place, in that they'd won everything already (except the Grand Prix Final, heh), but it would have been kind of ridiculous to retire from competition at the age they were at. So they pressed onward, into a quad that had lots of artistic brilliance but also mounting frustrations as the momentum shifted against them.
But then, they started off things on such an awful note the following season; the whole history of the quad might have been different if Tessa hadn't gotten injured before the start of the 2011/12.
EDIT: Also, this had been building for a while (arguably since the late Bourne/Kraatz years), but this was the moment that cemented that ice dance had eclipsed pairs in Canada, a situation I don't foresee changing any time soon.
