While some of the celebrities have known each other for 30 years, others have no friends in the castle at all.
My Mad Fat Diary actor Sharon Rooney and Industry star Myha’la, for instance, have fewer connections than the others.
And that can be a disadvantage. Remember Niko Omilana and Ruth Codd last year?
After they were banished early on, a theory spread on social media that they were voted out because the other celebrities didn’t know them that well.
But it can definitely go both ways.
Leigh-Anne Pinnock has said the fact she doesn’t know many people might actually help her.
“I think I’m at a slight advantage because people just know me as Leigh-Anne from Little Mix, and they don’t really know my personality that well,” she said.
What’s clear is that these prior connections are “exactly the sort of thing” that makes Celebrity Traitors so fascinating, as TV reporter Siobhan Synnot told me.
But – like Pinnock – she agrees that having loads of friends doesn’t necessarily end up helping you.
“Quite often in The Traitors,” she says, “that familiarity becomes a disadvantage”.
Players, you have been warned.
