He learned something he never expected to when he confronted the woman he loves about her potential affair with his brother. Now, Brady will divulge Nicole's big secret to Victor on the Thursday, Aug. 24 episode of "Days of Our Lives."

Brady (Eric Martsolf) was convinced Nicole (Arianne Zucker) was cheating on him with Eric (Greg Vaughan) on the NBC soap, and when he finally confronted her about it, he learned that what was going on between them was innocent. However, when he also told her he had found evidence which pointed at Eric when it came to who murdered Deimos (Vincent Irizarry), Nicole was suddenly flooded with memories from the night in question, and realized she was the one who had killed her former lover.

Since the shocking revelation, Brady has assured Nicole that he would keep her secret, and has warned her not to tell anyone else what she knows, even though she fears that the trail will eventually lead back to her. Since both Chad (Billy Flynn) and Sonny (Freddie Smith) were acquitted of the charges against them, an investigation will continue. However, since Sonny is once again free and he doesn't want to lose Nicole, Brady has told her the best thing to do is keep quiet.

Now though, he will find himself being the one who shares the truth very quickly, as he continues drinking after falling off the wagon. When his grandfather, Victor (John Aniston) sees him in the act again and goes to reprimand him, Brady will reveal that he knows the truth about Deimos' murder.

Victor had previously hoped they would find out who had actually committed the crime in the hopes it would help spring Sonny, and he already told Brady that he couldn't go to the police with his suspicions about Eric because they wouldn't seem legitimate because of his drinking, as well as the fact that he had been suspecting Eric and Nicole of an affair at the time. Since Sonny has been freed, Victor may not even really care as much about who killed his brother, as long as no one in his family foes down for the crime. However, when Brady tells him the culprit isn't Eric as he thought, it could pique Victor's curiosity more.

Brady will inform Victor of Nicole's revelation that she stabbed Deimos after he taunted her at the Marton House party about her losing Holly, and he claimed to have cursed her with the Ramses amulet to a life without children. She then snapped and grabbed a knife, stabbing him with it and killing him in revenge for everything he had done to her. Victor could be surprised by the news, but will quickly admit that it also makes sense that Nicole could be the culprit.

More shocking for Brady however could be a suggestion Victor makes. He has never cared for Nicole that much, and may tell Brady to do the right thing, which would be turn her in. If that is the case, Brady could find himself torn over what decision he needs to make.

"Days of Our Lives" airs weekdays on NBC.
