Ah, but why was Kevin ill in the first place? The plot thickens! A certain pro dancer who formerly went by the name "Rent-a-pro" exited the competition and almost immediately both Kevin and Pasha fall ill. Suspicious, no? Brendan clearly gave a "cold" type virus to both Kevin and Pasha in the hope that he might once again get to ride to the rescue and dance with one of the front runners! Now Trent wasn't actually ill this week, or at least not as far as we know, but the BBC would want to cover up any backstage rumours if it turned out that Trent was disgustingly healthy and Brendan took... further steps... to remove him from the training room.*
And yes, Tristan has been terrible as Pixie's pro partner. Do you know, I don't think I've seen him training her even once!
*I'm hoping people know that this isn't serious. I'm not actually accusing Brendan of poisoning people.
