When Tom said that they had just confirmed something during the commercial break and asked Dorothy and Tristan to come back out, I actually thought he was going to say that they miscalculated and that they were still in danger or possibly even the couple going home. I was already getting really angry as that would have just been a cruel thing to do. Sad to see them go, though, no matter the circumstances. I completely understand her reasoning, though. DWTS is hardly worth risking permanent injury.
It makes me sad to Tristan, though, because it is my understanding that the pros get paid based on how long they stay in the competition. They are out through absolutely no fault of his own. And he's such a sweetheart, too.
