Fake Jack/Marco (Peter Bergman) is ready to end Victor (Eric Braeden) and maybe even Gabriel/Adam (Justin Hartley) too it seems.

In recent episodes it has been revealed that fake Jack/Marco has been the responsible party for all the deaths in Genoa City that have accumulated over the last few months, starting with Austin's (Matthew Atkinson) at Abbott cabin.

It's likely that the criminal wants to add to that death toll just to ensure his cover won't be blown.

Victor Newman Won't Die Anytime Soon On 'The Young and the Restless' Because Of Fake Jack/Marco?

In the sneak peek video below for the episode airing today, June 26, fake Jack/Marco points a gun at Gabriel/Adam!

"If you're not on my side, you will be another loose end I have to deal with," fake Jack/Marco threatens.

In the episode that aired Thursday, Gabriel/Adam caught on that someone else was assuming Jack's identity since he tricked fake Jack/Marco by talking about a time they spent together that actually didn't happen to see how fake Jack/Marco would respond.

Meanwhile, Victor is taking precaution by hiring bodyguards to protect his family since he doesn't know what fake Jack/Marco will do next.

In the sneak peek video, while it is nice Victor cares about his family, Nikki (Melody Thomas Scott) is not exactly pleased he won't tell her what's going on.

"What are you protecting us from?" she asks him.

Then, the actual Jack (also portrayed by Bergman) will learn from Marco's lover (former lover?) Marisa (Sofia Pernas) that someone will die at Chancellor Park when Victor meets up with fake Jack/Marco.

"Someone is not coming out of there alive," Marisa shares with him in the sneak peek video.

Then in the video Victor is seen meeting with either the real Jack or the fake Jack. Things are going to get messy real fast!

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