His alter ego pops up in Last One Laughing for a fun mini-performance, which is how I recognised him. I loved Nick this series so I guess I'll have to do what the world's been banging on about for ages and finally watch Ted Lasso.
As for Cat, she had quite a popular song a few years ago that was all over the radio. I imagine she'll do very well out of her Traitors appearance.
If one thing's been established this series, it's that sportsmen are highly competitive even in parlor games and don't give a hoot about celebrity hierarchies the same way as the entertainment pros do. For S2, maybe they'll hire more sportspeople for greater anarchy!
