Jack (Peter Bergman) and Phyllis (Gina Tognoni) are about to get a bit smarter when it comes to combating against Marco (also portrayed by Bergman) on The Young and the Restless.

Why Is 'The Young and the Restless' Cast 'Getting Fancy' While On Their CBS Set?

All the Genoa City residents are frightened that Marco is going to come and off them just like he did to Austin (Matthew Atkinson), Courtney (Kelli Goss) and others.

According to Soaps, Jack and Phyllis will bicker more in the episode airing today, Aug. 4, since Phyllis is livid about learning Jack hasn't always been the man in her life in recent months. She is gunning for Victor (Eric Braeden) since he brought Marco to town.

With that being said, Jack and Phyllis will come up with a code word so Phyllis will always be aware that Jack is Jack.

In the sneak peek teaser below, Marisa (Sofia Pernas) will come in contact with Jack, but she fears that it's actually Marco.

"It is you, Jack, isn't it?" she asks him.

Later on, due to the storm, Marco will emerge and try to trick Phyllis, but it seems like she'll have the upper hand since she came up with a code word with Jack.

Also in the sneak peek, Phyllis is seen talking with Nikki (Melody Thomas Scott) as the Abbotts and Newmans attempt to find peace, but Phyllis is not fond of putting their differences aside.

"With all due respect Nikki, either you are drunk, delusional, or both," Phyllis tells Nikki.

Lastly, in the sneak peek, it seems like Dylan (Steve Burton) is questioning his relationship with Sharon (Sharon Case).

The Young and the Restless airs on weekdays at 12:30 p.m. ET on CBS.
