If Plushenko seemed harsh on T. Tatmianina, I think it could be described as such: Last winter, TT and Max did press conferences in Russia with Plushenko to hype his upcoming tour that they would be a part of. In the newspapers we saw numerous photos, including a shot of Plushenko holding TT up in a Pairs pose above his head, to generate publicity for the shows.
Just after that time, Plushenko's, shall we say "personal life", went in a new direction with a new girlfriend (that he is presently with), although he remained fully committed to his new tour. TT and Max decided not to do his tour, although they had a contract. An ugly dispute erupted in the press with threats of lawsuits. Soon after the US Champions On Ice tour began, with Plushenko a part of it, along with TT and Max. The pairs team shows up in the US, does maybe 4 of 5 shows, and then goes back to Russia, breaking their COI contract.
So, in Plushenko's mind, not only was his tour hurt - and his audiences disappointed - but now a second tour that he is a major part of (COI) is also hurt by their sudden withdrawal from performing.
