It seems that Dina (Marla Adams) will find herself involved in more drama in "The Young and the Restless." Spoilers reveal that she will overhear some shocking revelations in the coming episodes.

First, Zack (Ryan Ashton) will tell Abby (Melissa Ordway) everything as he speeds down the highway. He will confess that he was running intimate massage parlors and that eventually led to his prostitution ring operation. He will try and justify his actions and even suggest that he could give all that up for Abby. However, she will be too disgusted to even consider the idea.

This will lead Zack to show Abby who he really is. He will force her to leave the car with him, and when they are gone, Dina will appear at the back of the vehicle. It seems that she will know everything Zack did to Abby. Of course, there is a reason why Dina was in the backseat. It now poses a question of how her involvement will come into play later on.

Fans know that Dina is suffering from Alzheimer's, so there is no telling if she will still remember those details in 10 minutes. However, there is a chance that someone will try to get a hint out of her. She might say something that will lead the police to the place where Abby was last seen. This could help Paul (Doug Davidson) track down Abby along with Scott (Daniel Hall), who will be held hostage with her after he fails to rescue her.

Of course, Dina's wild streak should also be noted. Dina just burned down The Underground after all, and she even stabbed Nikki (Melody Thomas Scott) at a party. The chances of her slowing down are pretty slim as of now.

Dina will appear in Genoa City in Tuesday's episode and she will even get arrested. Before Paul will take her into police custody, there is enough time for something big to happen. Dina might be able to run into Zack as he tries to escape.

Previously, Zack framed Scott for Natalia's (Tina Ivlev) murder, so he would hardly have any reservations about killing an elderly woman. Then again, Dina could make her move on him first. She could kill him in self-defense, although she would certainly be okay seeing him get his comeuppance for hurting Abby. Dina initially pushed Abby to go after Zack, so she might feel partially responsible for what happened.

Over at the Newmans, "The Young and the Restless" spoilers indicate that Victoria (Amelia Heinle) will continue to make dirty moves and despicable power plays. It is clear that she thinks her old employees were to blame for Brash & Sassy's downfall. However, she had the final say in everything. Victoria only has herself to blame for her company's failure. She should have paid more attention in the beginning.

Fans can probably agree that Victoria did not do a very good job at running her business, but Victor (Eric Braeden) continues to shower her with praises anyway. He bailed Victoria out and forced Abby to report to her. When Abby tried to congratulate her sister, Victoria ended up gloating, making things worse for Abby.

Many viewers thought that Victoria's sudden personality changes were being caused by her health issues. However, this might be how she really is. The outbursts and selfish acts are perhaps part of her character now. People can change after all, most especially when people like Victor coddle them and place them in high ranking positions in the corporate setting.

Fans would certainly love to see Victoria get a taste of her own medicine, and there is a way that it could happen. She is definitely not the best nor the smartest when it comes to business, so whether or not she will succeed at Newman remains to be seen. It certainly might be more satisfying if she did, to make her downfall a lot more hard-hitting.

Victoria could be a big help as Newman tries to bounce back from the sex ring scandal. She could come up with some good ideas to handle the consequences and therefore help the company get back on its feet. Victor might even start trusting his daughter more. As he gets ready to fully retire, he might declare that he is ready to hand the whole business over to her. Yet, just before Victor does announce that, Adam Newman could resurface.

Knowing that Adam Newman is being recast, this might get the Newman patriarch to rethink the company's future. Instead of giving the company to Victoria, Victor could blindside her by putting Adam in charge. Victoria will definitely be outraged, while Abby will think that she had it coming.

Plus, there is the added fact that Adam is Victor's favorite, and he really would be the best option. Adam would be taking over without other business-related scandals on his shoulders compared to his siblings.

"The Young and the Restless" airs Mondays to Fridays at 1:30 p.m. EST on CBS.
