They haven't crossed paths again since one of them left Salem a few months back, but the time for Kristen (Eileen Davidson) and Theresa (Jen Lilley) to meet face-to-face again has officially arrived on Days of Our Lives.

The Truth About Brady & Theresa's Baby Is Revealed

When they were both last in Salem together, they were in a heated competition to see who could be with Brady (Eric Martsolf), when Theresa pulled out the trump card by revealing she was pregnant with his child. Unwilling to let her enemy carry the child she believed was rightfully hers, Kristen paid Dr. Mandrake to have Theresa kidnapped so her embryo could be taken--and carried by Kristen instead.

Now, Kristen is a mother--for the baby that Theresa and Brady now assume they never actually conceived. But unfortunately for her, the child could be at risk for a disease--one that only its biological parents can provide answers to. Now, because she needs more blood from Theresa, Kristen will order her lackey, Clint (Lucas Kerr) to once again appear in Theresa's life--and this time, his orders are to bring her back to Kristen's hideaway with him.

Melanie Seeks Proof For Her Theory

If Theresa falls for Clint's charms once again (he previously duped her into thinking they had a real relationship so he could keep an eye on her and make sure she didn't remember what happened to her, in addition to securing some blood plasma), it could prove to be more deadly this time. Not only would being brought to Kristen expose something, but seeing the baby she believed she had conceived alive and well--and in her enemy's arms--could cause Theresa to be killed after she's proven useful for Kristen's newest plot.

However, unbeknownst to Kristen and all of her henchmen, Melanie (Molly Burnett) has finally stumbled across what really happened--and is about to tell Brady he's a dad. Once he finds out the truth, his hunt for Kristen will commence--and if he is able to get there in time to save Theresa, there will be nowhere for Kristen to go that allows her to escape.

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