The Young and the Restless (Y&R) spoilers for Monday, February 16, reveal that Jack Abbott (Peter Bergman) and Billy Abbott (Jason Thompson) will have a showdown over a power grab while Daniel Romalotti Jr. (Michael Graziadei) considers his worst fear.

For starters, Billy will gladly retake the Chancellor throne and make himself at home again in his old office.

Although Billy will be proud of his accomplishment, Jack will have a big problem with his brother’s actions.

Jack may worry about the road Billy’s headed down, especially if he gets updates on Billy and Sally Spectra’s (Courtney Hope) apparent breakup.

Billy went after Chancellor and scored Newman Media for Sally, but Jack may wonder if he really thought she’d have a positive reaction.

Jack may argue that Sally can see the same red flags that he sees when it comes to Billy’s obsessive, dangerous behavior.

Although Jack will voice concerns, Billy will doubt that his brother is genuinely worried about him.

Billy will suspect that Jack’s angry because he wishes he’d been the Abbott to take Victor Newman (Eric Braeden) down instead, but Jack will surely deny that.

There’s no denying that Jack loathes Victor, so he certainly doesn’t mind the idea of him suffering.

That said, Jack will fret over the target Billy’s putting on his back and fear it could cause drama for the rest of the Abbott family, too.

Furthermore, Jack won’t think it’s right for Billy to swoop in and steal Chancellor from Nikki, but Billy may argue that she had no problem accepting it when Chancellor was stolen from him first.

While Jack and Billy face off, Y&R spoilers say Daniel will mull over his future and whether Tessa Porter (Cait Fairbanks) will really be in it.

Now that Mariah Copeland (Camryn Grimes) has been apprehended and will be receiving the proper mental care, Daniel may consider the possibility that it’ll lead to Tessa and Mariah’s reconciliation.

If Mariah finally lets her walls crumble and opens up to Tessa, it could change things.

Daniel found love again after losing Heather Stevens (Vail Bloom), but he may fear losing it all over again if Tessa ultimately reunites with Mariah.

The Young and the Restless spoilers say Danny Romalotti (Michael Damian) will get the latest Mariah news from Daniel, so stay tuned to hear his advice.
