She's been suspicious that someone is up to no good since learning Brady (Eric Martsolf) had been tranquilized and had some of his blood stolen, and now, after arriving at Theresa's (Jen Lilley), Melanie (Molly Burnett) will have all of her suspicions confirmed on Days of Our Lives.

Melanie Puts Her Foot Down

After getting Brady home from the hospital, she saw Theresa had sent him some text messages, and decided to confront her about harassing her ex-boyfriend. However, as she arrived at Theresa's door, she ran into Clint (Luca Kerr), who was on his way out-and their collision saw him drop two vials of blood.

Now, Melanie will become increasingly more suspicious about why Theresa's new beau has vials of blood, and will wonder if one contains Brady's-and she may demand answers about just what he is up to.

Theresa Confronts Melanie

What Melanie is not yet aware of is that Clint came back, once again on the orders of the creepy Doctor Mandrake, to continue doing some dirty work that ensures neither Theresa or Brady find out that they were actually expecting a child together-one which Kristen DiMera (Eileen Davidson) stole from Theresa's body after learning she was pregnant. Clint initially was only keeping an eye on Theresa to make sure she didn't remember being kidnapped, drugged and operated on, but has since been sent to collect blood samples from both her and Brady at Kristen's request.

However, Melanie's investigation could once again cast a large amount of suspicion on Clint-and the plot for Kristen could begin to unravel.

Days of Our Lives airs Monday-Friday at 1 p.m. on NBC.
