This is why V/M took unfair advantage of the break rule. They did not fall horrifically during the routine as Zhang did. I'm sure Tessa is in pain a lot, but not as horrifically as a pairs fall. Tessa's is a recurring injury that did not occur during the performance, which falls under the category of lack of readiness/stamina. Zhang & Zhang were justified in stopping and restarting without penalty. If it's not clear to the naked eye that someone has an injury, it needs to be explained to a judge or medical official. Tessa didn't do anything to indicate injury, she just skated around to the boards with big eyes and characteristic silence while staring at her coach. There's no guarantee that anything was actually wrong with her.
What V/M did is no different than a singles skater going into a jump, stopping, skating over to the boards, shaking out their legs and continuing the program.
With the logic of quasi-medical stoppages going unpenalized, then Ashley Wagner should have gotten extra points for injuring herself at GPF but continuing the program.
