I just finished that podcast.
I loved George on it...and I felt like he got a few - mostly subtle - little jabs in, and I think that is more of an indicator than anything said outright.
He mentioned being repeatedly unlucky, contradicting Toto's 'once', noted that "just drive" isn't as funny after a while...qualified his talking to Toto to 'most' days instead of his usual everyday.
He was also a little skeptical about Marcus's self-proclaimed ability to read George's mind during the races by saying he would test him. His reactions were mostly jokey, but to me they all held a grain of truth.
Marcus seems like a nice enough guy, but nothing he said really changed my mind about his competence honestly.
The other two were obviously trying to fix the narrative...the different garages, the communication bla bla bla. Understandable to want to try but also too on the nose...
