All that ‘I forgive you John’ by Constantine was to make him look good in the eyes of Maggie. Telling John he didn’t need to go to Greece was because he was afraid of what John might uncover. Now Steve and John need to fly to Greece right away, not tell anyone, and do some digging! Spoilers say that John and Marlena start to question some of the things Constantine was saying.
I absolutely cringe at the scenes with Constantine and Maggie. He is so disgusting and phony.
