She lied to him his entire life about who his father was, but now, Tori (Hira Ambrosino) will come clean to her son, Paul (Christopher Sean) about her previous time in Salem many years ago on Days of Our Lives.  

Marlena Demands Answers From Tori

The truth that she and John (Drake Hogestyn) had previously been involved during the days where she worked in Stefano's (Joseph Mascolo) home was first something that Will (Guy Wilson) stumbled across as he tried finding dirt on Paul to get him out of town and away from Sonny (Freddie Smith). He initially mistook a photo of Tori at Salem Lake as proof that Paul was a DiMera, but after seeing her interact with John for the first time in decades, he realized the actual truth--but still kept it a secret in the hopes it would keep Paul from staying in town.  

However, after Sonny found Will's initial plans at exposing the truth in an article, he warned Paul that his mother had been lying about his father dying many years ago--and now, Paul wants answers from Tori. She will be reluctant to tell him everything, but may finally decide to tell her son why she kept the truth hidden.

Unfortunately for her, Paul won't be the only one who learns the truth however--John will also find out he has another son he never knew about--and he too, will demand answers about why something so important was kept from him for so long.  

What remains unclear for everyone involved in the saga is how it will affect Tori and Paul's plans to leave town. Not only would staying mean that John's relationship with Marlena (Deirdre Hall) could be strained, but Paul sticking around could bring some new problems for Sonny and Will's already troubled marriage.
