[The Penguin]

the twins have an argument straight after leaving the diary room and on a day when the housemates are being set a lot of tasks and not soon after it there is no tension at all between them and they are laughing about the very next task with Gareth despite supposedly having a personal argument which results in tears a little bit earlier.....yet all the housemates believe it and continue to believe it
I know it's different from the perspective of a viewer but I don't think it takes Hercule Poirot to put that one together
