Last week on "The Young and the Restless," Devon and Hilary's wedding went through without problems as Neil decided not to show the incriminating video of Devon with another woman at his bachelor party. However, Neil was still bent on revenge, and while on a hike, he showed Hilary the video. Hilary thought it was faked, refusing to believe that Devon would cheat on her. Meanwhile, Devon got worried when he couldn't reach Hilary on her phone, and on Friday, a police officer told him that Hilary's room key was found on the trail and that she may have fallen. 

Meanwhile, Jack was able to hold Marco as a prisoner in the Abbott cabin, with Marisa guarding the impostor. Although he was very angry, Jack was able to stop himself from killing Marco, and he only had him tied up to stop him from escaping. While Jack was out, Marco tried to get Marisa to untie him by telling her that Noah's family will never accept her. Marisa was not impressed with his threats and told him that she really wanted to see Jack kill him. 

Another person with a lot of anger toward Marco appeared at the cabin — Phyllis. Because she has been furious with him since learning that she had been sleeping with Marco — thinking he was Jack — during their honeymoon, Phyllis wanted nothing more than to kill the impostor. But Jack arrived and took the knife from Phyllis, and Phyllis and Marisa had to convince him not to kill Marco. For now, he lives.
