Fake Jack/Marco (Peter Bergman) weaved quite the messy web by saying Gabriel, who is really Adam (Justin Hartley), is his son.

Aside from that, Fake Jack/Marco is still not acting as the real Jack (also portrayed by Bergman) would, which is alarming to Phyllis (Gina Tognoni) as well as Kyle (Lachlan Buchanan) and others.

In the sneak peek video below for the episode airing today, June 24, Phyllis confides in Gabriel about how things with Jack have been since they eloped. He acts differently.

Gabriel agrees, "he is changed," which spurs Phyllis to ask, "Why would you say that? You didn't know the old Jack."

Meanwhile, Billy (Burgess Jenkins) and Kyle want Gabriel to have a DNA test done since they don't believe he's an Abbott.

"We think Bingham [Gabriel's last name] needs a DNA test," Billy shares on behalf of himself and Kyle with Jack's doppelganger.

"I absolutely agree," fake Jack/Marco states, but he'll be attempting to pull one over on them to keep his web of lies concealed.

According to Soaps, fake Jack/Marco will then confide in Gabriel/Adam about the DNA test problem is fixed. He'll apparently bag Kyle's glass since it has Kyle's DNA on it. Kyle is the real Jack's son so the results will be exactly what fake Jack/Marco wants.

Adam will then ask fake Jack/Marco about something that never actually happened to see how he responds, which leads to him knowing the Jack he's been talking to is not the real Jack.

Plus, Lily (Christel Khalil) has her own problems to face after cheating on Cane (Daniel Goddard) with Joe (Scott Elrod). Lily asks Joe not to say anything, but will he keep his word?

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