I think Nico’s look in that last gif says it all really.
You can’t just say “We’re not friends” and then be all chummy and not expect it to backfire. I mean, they’re weren’t even being that friendly when the season started so Lewis needn’t overdo it. He’s clearly had a bollocking from Mercedes *cough*Niki*cough* about PR and is going the extra mile to smooth things over.
But it doesn’t look like it’s working.
