Jonathan Jackson returns to the role of Lucky Spencer on "General Hospital" just in time to discover he is being betrayed by his fiancée Elizabeth (Rebecca Herbst) — and his dad Luke (Anthony Geary) knows and hasn’t told him! "Luke is struggling to decide whether to tell his son or not," Tony tells ET. "Their relationship is quite volatile. I see that there is a train wreck about to hit the Spencer clan -- and that is always exciting in daytime: a lot of passion, a lot of hurt feelings and a lot of fighting. I love me some fights!" "The upcoming stuff has to do with the inevitable reveal of that betrayal and what that is going to do their future, which is unknown and what that is going to do to the Spencer family as a whole," Jonathan adds.
