I'm with you, Karne. I think the move shakes up Kovtun more than Artur. "Kovtun's jumps are unsustainable in the long term" is probably too exaggerated/negative. TAT either wants to hog all the good skaters in her group, or she's... deliberately trying to sabotage Artur so that he won't be a threat?! (I really hope it's not the latter...) Either way, that means TAT doesn't see Artur as a total has-been/non-threat.
I'd be more worried about how TAT can manage her time between Artur and Kovtun, rather than Mishin managing his group. And they better make that Hollywood movie about the Yags-Plush rivalry soon.
