Columbo
Never again
I don't get why people would want to see Lawson continually flog himself over the Cat situation. It would actually be really insincere if he did. He has decided to be with Cat. He knows it wasn't done in the best way, but that's life. He can't change it. It is what it is. He is moving on. Why not? I certainly think he would be a hypocrite if he said he liked Cat more and wanted her but then pretended to be heaps cut up about the cheating aspect.
Maybe one of the housemates should randomly talk about Candice and see how he reacts so we can truly know if Lawson has moved on from being a cheater.
