All throughout 2002, the secrets surrounding Jack's birth and identity cause disaster to literally hang over Todd and Blair's marriage. Gabrielle Medina, whom Blair hates, finds out that the child is alive, and blackmails Todd into giving her a job. Blair thinks that Gabrielle is blackmailing him because Todd has gone through some "illegal procedures" in "adopting" their baby. But Todd's deception is discovered when baby Jack develops aplastic anemia, just like Starr had, and Todd has to bring Alex Olanov to town to, once again, be the bone marrow donor. Sam Rappaport, learning from Nora that Alex had been Starr's bone marrow donor too, puts everything together and tells Blair the truth, that Jack is her biological son and that Todd lied.
