I guess JOhn has forgetten how he kept Cristian a secert from Natalie. He didn't bother telling her Cristian was alive and went on to sleep with her, knowing she'd never have bedded him if she knew the truth, and yet he goes on and on about her lies in regard to Liam. I hope by the time the truth comes out, Natalie doesn't want anything to do with him and bars him from Liam's life.
