There's no favoritism regarding coach, stop that BS right away. It's bad enough to see some stupid Yuzu fans thinking that Brian prefers Javi just because Javi won Worlds twice, there's no need to make up stuff like this. M-F loves them both, and V/M have a good influence on P/C. And for good reason! 27-year old, with more experience and more titles and so on... it pushes them to work harder and make progress. V/M have praised P/C more than once before and the two duo get along with no problem.
I'm happy for P/C to have done so well and grab silver.
I'm gonna summarize it (if someone wants to make full translation, please do it

)
They mainly talk about how they just want to skate their own style. Talking about how in ice dance, rules are very complicated and changed every year. They want to do their own style and are attracted to music that have irregular beats (not sure if it makes sense in English, but basically, they mostly like to skate on unfamiliar music), but they adapt because the rules do not give total freedom on music choices. They also mentioned that Ice Dancing should gradually become more about dance than about sport. For example, they were inspired by "Le Parc" from Angelin Preljocaj for their Mozart FP because of the way the dancers move.Regarding the costumes, it is said that FS costumes can be subject to teasing. Something that Guillaume admit is true, but that for figure skaters, to have sparkly costumes is perfectly normal.
This season, pants are allowed but in the SD only. Something that Gabriella regrets because she sees no reason why they should be forced to wear a dress otherwise. Basically, she calls out the lack of freedom the ice dancers have when it comes to costumes (understandable imo).
They also talk about the complexity of ID scoring. Guillaume calls it a "700-page massive book", with the requested patterns and rules... and it changes every year, so it's quite complicated. But they try to make the best of it at doing things that are unexpected and not forbidden in the rules yet. Because you stand out more at being original.
And last, they make comments on French commentators Nelson Monfort et Philipe Candeloro who are known to make inappropriate comments (not gonna quote

) and create unnecessary drama (which is true as well, I hate them). P/C don't let this faze them but it annoys them that come commentators like to create fire for no more reason than creating unnecessary drama.
