I think he was frustrated too. Helen is clearly struggling with self belief at the moment and he must spend all week trying to build her up. And then pretty much all the judges commented on how the dance didn't have enough self belief.I think it was spur of the moment on Gorka’s part and probably came from frustration at the Judges comments and scores. There are couples who are fawned over and overmarked and couples who are picked up on technicalities and undermarked. It’s ‘his’ dance and I think he thought it would be Helen’s breakthrough.
I don’t think for a second it didn’t come from anywhere but a good place, he seemed really frustrated. I hope it doesn’t damage their professional or personal relationship though
Now my cynical head says that's pretty suss and clearly the narrative the producers have been told to push to further her journey, for all 4 judges to use that exact phrase.
BUT I think Gorka felt he had to say something because he actually understands what she's feeling.
