"I know Rob very, very well. I mean, I've sat next to him as he's had a colonic."
That was Romesh Ranganathan , reminding us - in case we were in any doubt - of his close friendship with Rob Beckett in the opening episode of The Celebrity Traitors.
His words sum up the key difference between this series and the regular civilian version. In Celebrity Traitors, the players aren't just on-screen competitors - many actually know each other outside the show.
Lots have worked together, and some are even friends. And those previous connections can have a huge impact on the show's dynamics.
It's also partly why it is quite so delightful to watch - as friendships unravel, and former co-stars turn on each other.
We've been unpicking the six degrees of separation. Here are some of the connections we've found - if you spot any more, we'd love to know. Get in touch with your thoughts in the comments section below.
The dynamic between Rob Beckett and Romesh Ranganathan is one of the most enjoyable to watch play out this year.
As well as being great friends in real life, they have also worked together repeatedly, including in their travel show, Rob & Romesh Vs.

"I mean, he's just as easily going to be on my side as he is going to twist the knife in my back given the opportunity."

They’ve also worked together on the TV show Travel Man.
Lycett is also friends with Joanne McNally , external - he's described her as "one of my favourite people in the world".
But those loyalties could be about to be tested, especially now that Acaster has been recruited as a traitor (anyone remember how things panned out for "good friends" Alan Carr and Paloma Faith...?).
There are SO many comedians in this year's series.
And they are all likely to know each other. In addition to the alliances above, Joe Lycett was on the TV show Last One Laughing with Rob Beckett .
Joanne McNally and Romesh Ranganathan appeared on game show Unacceptable together, and James Acaster went on Ranganathan's hip hop podcast.
Speaking ahead of the show, McNally insisted she and her fellow comedians "haven't been in cahoots at all".
"We know that we're more than willing to throw each other under the bus," she said.
As for Acaster, he's admitted the other comedians are his “biggest threat” when it comes to being detected as a traitor.
