yes, Jason knows that his biological mother is Susan Moore who was once married to Scott Baldwin..... but Monica is the mother who raised him and adopted him, so to Jason, the only mother he knows is Monica.
I LOVE EVERY scene between these two and Monica IS HIS MOTHER!!!!! It doesn't matter whether she gave birth to him or not. I can't believe that Guza REFUSES to write for the character of Monica. This is why I cannot STAND Robert Guza, Jr. the Head Writer of GH. Jason needs his mother--we all do. There should be MORE of these scenes between these two.
Jason's future was clouded from the start. Monica didn't want him in the QuarterMaine house, when he was a child. Her Susan Moore insecurities carried on longer after Susan's murder.
Oh it's worse. First Dawn, then the Jason she raised, then AJ, than Alan, than Emily and then Michael. Oh don't forget her ex-neice in-law Georgie... The Slaughter of the Q's
