Yes, I noticed that in Traitors Ireland, but had wondered if it had crept in from other overseas iterations of the show (I’ve only watched the UK and Irish ones)?
In the UK ones, mentions of the ‘turret’ seemed to be doing the same work as the term the ‘conclave’ — in the Irish version, of course, there was no turret because Slane Castle doesn’t have any. The traitors supposedly met in the dungeon (or a set that had been made to look like one.)
