The Young and the Restless (Y&R) spoilers update for Monday, February 16, reveals that Abby Winters (Melissa Ordway) will ban Mariah Copeland (Camryn Grimes) from Dominic Winters (Ethan Ray Clark) forever and kick the kidnapper out of her home.

At Crimson Lights, Mariah will be out on bail following her arraignment, but she’ll have to wear an ankle monitor and stay in Sharon’s custody.

Sharon will be grateful to Christine Blair Romalotti (Lauralee Bell) for taking Mariah’s case.

Despite accepting Christine’s advice to plead not guilty, Mariah will think she should change her plea to guilty instead.

Mariah will feel terrible about what she’s done and will walk Christine as well as Sharon through the whole ugly story.

There’ll be a discussion about the stranger who looked like Ian Ward (Ray Wise) and how Mariah got it in her head that she had to kill him.

Mariah thankfully didn’t, but she couldn’t fathom bringing that kind of evil around Aria Porter-Copeland (Maddie and Millie Ingle) and checked into the Boston clinic soon after.

That’s where Mariah started hallucinating Ian and his horrible guidance, so she’ll divulge all this to Sharon and Christine.

It’ll be obvious to Christine that Mariah needs treatment rather than time in a prison cell, so she’ll want to use an insanity defense.

Y&R spoilers say Sharon won’t blame Mariah for how her trauma has affected her.

That clinic in Boston wasn’t the right fit, but Sharon will feel confident they can get Mariah the help she needs.

After Tessa Porter (Cait Fairbanks) stops by the Chancellor mansion and gets updates on Dominic seeming fine all things considered, she’ll head to the coffeehouse.

Tessa will have an awkward, emotional interaction with Mariah, who’ll question her wife about Daniel Romalotti Jr. (Michael Graziadei) and whether he did what Mariah asked him to.

Mariah wanted Daniel to watch over Tessa, so Tessa will confirm his support without admitting he’s more than a pal.

After Mariah brings up the divorce filing that she heard about from Sharon, she’ll think Tessa knows what she needs.

Tessa will get frustrated over Mariah pushing her away again, so she’ll walk out the door to avoid any more pal.

At the athletic club, Daniel will seem anxious about things changing with Mariah back in Genoa City.

Although Daniel will feel like his feelings aren’t as important as everything else going on, Danny Romalotti (Michael Damian) will have sympathy anyway.

While Danny gives Christine news on Daniel’s Tessa love dilemma, Daniel will catch up with Tessa elsewhere.

Since Tessa will be crying after her interaction with Mariah, Daniel will embrace her and will promise to help her figure things out.

At the Chancellor mansion again, Abby will let her anger explode now that Dominic is safe and she doesn’t have to focus on the search anymore.

When it comes to whether Mariah should land in prison or a mental health facility, Devon will point out it’ll be in the judge’s hands. Even so, Abby will worry about the judge potentially getting it wrong.

Sharon will ultimately bring Mariah to the door, so Devon will let them come inside.

Abby will flip out over Mariah being there since Dominic might realize it and get upset.

Mariah will insist she had to come offer an apology and will make it clear that she knows what she did was wrong.

Although Mariah will hope for forgiveness someday, Abby will push her to get out and will ban her from any further contact with Dominic.

The Young and the Restless spoilers say Mariah will remain on Abby’s bad side for the foreseeable future, so don’t miss what’s in store.
