P/C were never uncomfortable accepting to train with V/M, they welcomed them with open arms... to quote Scott's words.
But to put everything into perspective :
You have a team ranked 13th at Worlds. They are propelled to number 1 in a year. That never happens. They miss half of the next season due to injury, yet come back and win in World Record fashion. Then one of the biggest Ice Dance teams join their camp : they are very appreciatted and extremely popular which can be understandably indimidating. The face-off doesn't go as planned because of many many mistakes BUT also because you are almost "inexperienced" in comparaison to a 2-time Oympic medallist team (1Gold and 1Silver !) and you choose to experiment a difficult FD this season, judges had a hard time accepting it. Remember that 2 years ago they were 13th...
The Olympic season being what it is, it's competitively tense, everyone is being pressured by the fans, the expectations, the federations, the scrutiny, the fact that they both went to compete with a 15, 20-point lead almost. Again 3 years ago, nobody knew them outside of the small FS world. They handled everything very well, and I believe whatever was said that P/C were trained like crazy physically and mentally. After the Olympic SD, which they handled like champions tbh, they were asked : "Did you hear the CAN score ?". Guillaume said yes, but said that it was not a factor at all, because what the other do do not affect them or their performance and that's why they managed to score so high all season and deservedly so. They performed every single time.
I'm somehow amazed by a team that went from 13th to 1st in one year, proved that it wasn't a fluke the next year even with a concussion (and even separating themselves from the rest of the field), managed to handled the crazy competitors that V/M are despite starting with a 10-point loss, managed to catch them and even overtaking them this year, when they started at the Senior level 7 years later.
If tomorrow, a top team were to ask to move to Montreal P/C would say no I think, and so will H/D too. These 2 teams have accumulated enough experience, learning in 2 years what some others learn in a lifetime, and it will probably set them apart. This will be the top 2 in Montreal for the years to come and that's enough. And maybe top 2 in the world for what we know (especially considering what they both did at Worlds).
I'm one to think that the Gabdois coaches might have been very careful when speaking to the press, even looking distant, because one side could obviously attack the other (and vice-versa) and YES, MF&P are Canadians, which means that if you rave about P/C in a Canadian article while V/M scored less all season, some would have been outraged and the "Marina gate" would have resurfaced. The same would have happenned if role would be reversed and they were all training in France.
However, looking at the teams, they were so trained, so impeccable and all looked so prepared. P/C adressed some confidence issues after Worlds 2017 and it feels like they are gone for good, and they even looked extremely confident at GPF which allow them to win, and knew that they could do it. V/M scored less but unlike some of their weird fans on twitter, they actually took the time to fix what could be fixable and get the job done. Nothing like 2014. They may not have been communicating much due to being very competitive, but there was respect if anything.
The rest is unknown to our eyes, but as far as what I saw on the ice, the coaches did a fantastic job preparing them and nothing will change it. If a coaching change were to happen, okay. It's part of the life of an athlete anyway, they'll do what's best for them, choosing what will be the most efficient way to create, be competitive and stay at the top.
All I can wish for them is the best, wherever that may be...
(...And I also wish for a "Sleeping at Last" FD one day but that's another story)
