Fake Jack Causes Problems In Genoa City On 'The Young and the Restless'?

He is befriending Victor (Eric Braeden) while upsetting and stunning his family especially Ashley (Eileen Davidson) and Billy (Burgess Jenkins).

The family is unaware that Jack is not himself and is currently an imposter so they will confront him about stepping down from Jabot for the time being, which will lead to Billy being fired.

Soaps reported that Phyllis (Gina Tognoni) invited Ashley, Billy, Kyle (Lachlan Buchanan) and Abby (Melissa Ordway) over for cocktails, but things head south quickly as soon as Ashley and Billy suggest Jack removes himself from Jabot.

Fake Jack will call them all traitors and order them to leave after he showers Phyllis with tons of over-the-top affection in front of them, which will confuse them along with the rest of his bizarre behavior.

Phyllis will try to make her husband realize that his family is just concerned, but he will remind her that her loyalty should only be with him.

Ashley, Billy and Abby will be at the Club and plan to call for a board meeting so Jack can be voted out.

Plus, Victor will meet with Fake Jack at the confessional, sharing he is not pleased that Fake Jack returned earlier than planned.

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