In Monday's episode, David prepares to celebrate his birthday, but the occasion is overshadowed by the continued speculation over who Jacob's new girlfriend is.
David and Leyla decide that Gabby is the most likely option. David also shares the theory that Jacob and Gabby are keeping the fling quiet because they feel guilty over the memory of Jacob's late girlfriend Leanna Cavanagh.
Although Jacob denies all of this, he's forced to go along with it when David arrives home unexpectedly and interrupts his latest afternoon of passion with Victoria.
After Victoria rushes upstairs, Jacob makes out that David is right and Gabby is the mystery lady in the house. Victoria cringes over Jacob's excuse, sensing that he's making the situation worse.
