Watching Emmerdale episodes from 2004 and these two seemed genuinely in love, why was Robert so full of hate for her when he came back. Karl and sammy had very good chemistry together and from what I can see he was the one who cheated on her so him being the bitter one makes no sense.
The current Robert worshippers will never have seen Karl's Robert though. I doubt this actor will do as well after Emmerdale.
