He has been working on building a better relationship with the father he never knew existed, but after another confrontation with Will (Guy Wilson), Paul (Christopher Sean) will begin to question John's (Drake Hogestyn) past on Days of Our Lives.

Paul and Brady's Relationship As Brothers Gets Off To A Rough Start 

The father and son learned about one another's existence when Paul was in Salem previously, after his complicated shoulder surgery which ended his career, and Will's article where Paul finally came out publicly for the first time. Since then, John followed his son to San Francisco, and convinced him to come back to Salem so he could get to know the family members he never knew existed. 

However, Paul's visit has been mainly occupied by time with Sonny (Freddie Smith) again, something that didn't sit well with Will when he returned home from interviewing in Poplar Bluff--and the two had a major confrontation which saw Will hurtling insults at Paul about his background, especially his mother.

Will Manipulates An Explosive SItuation 

Now, with the knowledge that his mother must have had a reason for telling Paul his father was dead, and not letting him know of his existence for as long as she did, he will begin to wonder if John wasn't the same man back then as he appears to be now--and this will cause him to question his father about the past. As a result, he may not like what he has to hear about how his conception came to be--and it could hurt the fragile relationship they've started to build.  

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