What's next on The Young and the Restless

Jack's (Peter Bergman) not surprised by Victor's (Eric Braeden) attacks on him, but he may feel differently about the rest of the Newman clan to a higher standard. On Thursday's show, watch for Jack to hold Adam (Mark Grossman) and Chelsea (Melissa Claire Egan) accountable for their actions. Jack may not know that Chelsea didn't know about the negative story on Jabot, but she's still in the Newman camp and plays a key role at Newman Media.

Victor may not bat an eye at going after Jack because he doesn't like that Jack was involved in Nikki's (Melody Thomas Scott) life when she was having trouble. But do Adam and Chelsea feel the same way? Jack may find out.

Strange bedfellows

Billy (Jason Thompson) and Phyllis (Michelle Stafford) have a complicated history, but the Abbott heir cut ties with Phyllis earlier this year after they fought over, among other things, Phyllis wanting Daniel (Michael Graziadei) to have a role at Abbott Communications.

Now, however, the Abbotts see Phyllis as someone who can be an ally in terms of Victor's attack on them. She just may be opening to finding new friends in Genoa City. Recently, Phyllis got into bed (literally) with Cane Ashby (Billy Flynn) and (figuratively) with Victor. Neither venture has gone well.

On Thursday's show, watch for Billy to strike a deal with Phyllis. She's in a position where it may benefit her to say yes and be an ally to the Abbott clan. Could Phyllis be the solution to the Abbott family's battle against Victor?

A Summer wind

There have been mentions here and there, but Summer (Allison Lanier) hasn't been on the scene since moving to Italy to run Marchetti Fashions. As Marchetti is a division of Jabot, she stands to have her life affected by the Newman/Abbott war. On Thursday's show, watch for Kyle (Michael Mealor) to send a message to Summer. As Victor's granddaughter, Summer could play a key role in getting Victor to back off from his ongoing attacks against Jabot. Does this mean a "Summer" wind will be blowing back into Genoa City?

Lanier's return could add a new dimension to Kyle's dynamic with Claire (Hayley Erin), which recently took a new twist when the two found common ground in terms of their distrust and/or dislike of Audra Charles (Zuleyka Silver).
