So... I did rewatch it, thinking, "focus on the program not on the costume malfunction".
Well, aside from the twizzles which got downgraded in GOE, it was far from a disaster... I mean truly really far from what I saw that was written. Their skating skills are off the charts though. They did rightfully get a Pst level3 when Gaby was doing her twizzle she was not stable (well, I don't want her top to get off so...) but the rest was actually... good. Despite critics, I mean try to even fight me on this one.
PCS wise, they got the highest on Skating Skills, Transitions and Compositions. Obviously certainly not on Performance and Interpretation.
Interview on the mixed zone with French TV they were pissed and not hiding it : "What happenned ?" Gaby said : "My costume oppened" and nothing else because they was nothing else to say. "Did you hear the Canadian scores ?" and they made such a face like Why the f*** would we even care ? Guillaume : "Yes, but it doesn't matter, it's not a parameter". They were extremely calm, visibly pissed and did not want to speak for nothing so they stopped talking.
