Sometime during this whole fiasco, Jack learned from Melissa Horton, who he had turned to when his marriage had gone sour (not realizing that Harper was trying to frame her for poisoning Kayla), that he was adopted. He turned his back on Harper (who he found out was sterile.) He learned that Jo Johnson was his mother, and Steve and Adrienne are his siblings. It was initially hard for him to accept, but Adrienne convinced Jack to at least try, and he made his mother's Christmas when he extended an olive branch...in the form of expensive emerald earrings.
