She's managed to keep the fact that she stole Brady (Eric Martsolf) and Theresa's (Jen Lilley) baby a secret for months, but now, Kristen (Eileen Davidson) will be forced to confess all on Days of Our Lives .

Brady & Kristen Battle Over Baby Christopher

Melanie figured out the truth when she examined Theresa's blood plasma, and told Brady the truth. He then went to Kristen's castle in Italy to confront her about what she did, only to turn up empty handed because she was keeping his son hidden away in a secret room. However, Melanie managed to sneak over to Italy as well, and got herself into the castle--finding the baby.

Now, she and Brady will be forced to try and confront Kristen with the proof they needed--and she will finally need to confess to the entire truth about what she did--which included learning about Theresa's pregnancy, having her kidnapped, getting the embryo stolen and implanted into herself, and then fleeing town.

Brady Seeks Victor's Help IN Tracking Down Kristen

However, Brady and Melanie could be in for their biggest shock yet if Kristen admits to the health problems baby Christopher has because of his immunity disorder. They'll be even further shocked if she reveals what she had planned to do in order to make sure he would stay healthy--having Clint (Lucas Kerr) trick Theresa into following him to Italy--where he would bring her to the castle to have bone marrow taken so it could be given to the baby. Afterwards, so she wouldn't be able to reveal Kristen as a baby thief, the plan was to have her killed.

Now, Brady and Melanie may need to try and save Theresa before Kristen gets her way.
