The mystery surrounding the suspicious things happening with Theresa (Jen Lilley) and Brady (Eric Martsolf) has been plaguing Mel (Molly Burnett) for a while, and now, her investigation into it will finally reveal the shocking truth about what happened with them on Days of Our Lives.  

Melanie Seeks Proof For Her Theory

After Brady was attacked and had blood taken from him and Melanie realized that Clint (Lucas Kerr) had also drawn blood from Theresa, she looked into all of the possibilities for why someone associated with a fertility doctor would take blood from the two. And even though it sounded insane, the only answer that she could keep coming back to was one related to the baby that no one believes existed when Theresa told Brady she was pregnant.

However, now, Melanie could stumble across the exact piece of the puzzle that she was missing to make the possibility that someone had implanted Theresa's embryo in themselves and carried the child as a surrogate make sense.

Melanie's Suspicions Increase When She Catches Clint

She couldn't figure out why someone would have taken the embryo from Theresa, and the whole mystery surrounding Clint and his mysterious boss, Dr. Mandrake made even less sense, because they were watching her to make sure she didn't remember anything that happened to her. But now, Melanie may finally find the connection that was missing--Kristen (EIleen Davidson).

If Melanie can find a connection between Kristen and Mandrake, she will finally realize what really happened--Kristen hired Mandrake to steal Theresa and Brady's embryo, and had him implant inside her. And with the amount of time that has now passed since the entire incident, it will mean one thing--Theresa and Brady have a child together, and Melanie will make sure they learn the truth.
