This year, they all had to take a Traitor's Oath before Claudia handed them their cloak which included this line "Do you vow to keep the identity of your fellow traitors a secret?"

They can come very close to it during banishment though it seems. Last series Kieran was directly influential in Wilf's downfall during his banishment with his 'a parting gift' comment during his vote at the last round table. I believe Wilf would have won otherwise.

Hopefully none of that this time around but it's always worth looking at the vote of a banished Traitor particularly towards the end of the series. They missed a trick when Ross voted for Andrew.
