The Young and the Restless spoilers for Wednesday, September 10, have Jack being concerned about a cryptic message, Caine ruining Sally and Billy's big night, and Phyllis taking control.
What's next on The Young and the Restless

Jack Abbott (Peter Bergman) is a man who is keenly aware of his enemies and his surroundings. If he is worried about something, it's got to be something significant. On Wednesday's show, watch for Jack to be concerned about a cryptic message.
Will this missive be connected to the ongoing mystery of what Cane is or isn't going to do with multiple businesses in Genoa City? Jack believes, for now, that Cane has put his plans on hold. But has Cane truly decided to do that? If this message is serious, we expect Jack to take action to protect his family, his company, and his other interests.
Party pooper

Sally Spectra (Courtney Hope) and Billy Abbott (Jason Thompson) have been planning the launch party for Abbott Communications for a while. Is Genoa City ready for another all-star gathering of the show's top players, like they did when they gathered for Nikki's birthday party and Cane's gala in France?
Maybe not. On Wednesday's show, watch for Cane to ruin the couple's big night. Is Cane out to show that he's the only one who can throw a shinding? Or does he have a reason for manipulating the outcome of Abbott Communications's launch party? Cane may want in on a piece of the pie with Billy and Sally's new company, so he has a media power base under his control.
The driver's seat

Phyllis Summers (Michelle Stafford) isn't one to take things while sitting down. She recently talked to Michael Baldwin (Christian LeBlanc) about their relationship at Crimson Lights, hoping to move forward and properly reconcile their friendship.
On Wednesday's show, watch for Phyllis to take charge. She also showed she was capable of that by walking up to Billy and telling him that Cane didn't want him around. Phyllis being impulsive can land her in hot water. She learns from her mistakes, but then, she, arguably, sometimes forgets. What's going to happen when Phyllis takes charge? We predict: drama!
