Which UK S3 Contestant caused the biggest shift in your opinion of them

For example from the very first episode with the train scene when Dan was laughing about how he wouldn’t get off I immediately thought he was gonna be the most unlikeable person this series. Doubly with how he reacted to Jake getting annoyed with people that didn’t get off the boat.

However when Tyler was first introduced I genuinely thought he was being telegraphed to be a fan favourite as well as a traitor and that Leanne would have similar vibes to Alex from S1 being intelligent and logical to the point of it being threatening for the traitors.
