'Young and the Restless' Thursday spoilers, recap: Devon and Hilary's wedding day

Thursday on "The Young and the Restless," Jack told Ashley that Victor is convinced that the Abbotts are plotting against him. Ashley wondered who the mastermind is and thought that it's someone who knows Victor's weaknesses. Jack thought that maybe it's Gabriel, but Ashley said that whoever's doing this seems to have a personal grudge on him, so maybe it's not Gabriel. 

Meanwhile in Paris, Adam and Chelsea celebrated with champagne, and Chelsea said that she wanted to forget the real world. He told her that he had found their dream home, but Chelsea reminded him that she agreed to stay together for a week. Adam said that he'd do everything so they can get what is rightfully theirs, but for now, they have to stay in Paris and forget about the past. Chelsea checked on Connor and Adam got a call from Jack, who asked him how long he's been planning the Paragon Project. Adam said he doesn't know anything about it, but Jack didn't believe him. Jack urged him to come home and help him figure out who the culprit is, but Adam told him that he has no plans to go back to Genoa City. 

At the Club, Devon was giving Hilary a diamond necklace when Colin arrived. Colin made cryptic remarks about faithfulness and eternal love and said that he would love to buy his wife a necklace like that. After Hilary left, Devon figured that Colin was trying to blackmail him. Colin said that he didn't have to pay him — he could tell Hilary the truth about the girl from the bachelor party, if that's what he wants. 

Nikki found Hilary trying to write down her vows, and Nikki told her that she ought to be careful today because Neil appeared to be far from fine. Nikki worried that he might cause problems today. 

Later, when Neil gave Hilary his best wishes, she demanded to know what he was planning to do to ruin her special day.
