Thursday on "The Bold and the Beautiful," Ivy thought about the disturbing images on Aly's secret board in her closet. She tried to call Aly but was unable to reach her. 

At the mansion, Maya was spooked about what was found in Aly's room. Wyatt, Liam, and Rick didn't blame her for being scared. Thorne arrived and Rick introduced him to Maya. Thorne told her that he admires her courage and is proud that she's going to be a part of the family. Rick told him that he couldn't have arrived at a better time — Aly has regressed, and she's getting worse. Maya said that Aly has been fixated on her and Steffy, and Rick felt like he's partly to blame and said he's sorry. Thorne asked if Aly has started seeing Darla again, and Liam said that Aly did mention that she's been talking to her mom. 

Liam was thinking that Aly's condition was being aggravated because she was spending too much of her time alone, and she was taking out her anger on Steffy and Maya. Thorne said that he'd take Aly with him to Paris and get her the help she needs. 

By the roadside, Aly had a tire iron in her hand and she approached Steffy. Aly said that she had to do this — she couldn't let Steffy and Maya ruin everything. Aly swung and the tire iron skittered across the ground. Aly picked up a rock and stood over Steffy. Ivy pulled up in her car as Aly was about to strike Steffy with the rock, but Steffy grabbed the tire iron and hit Aly with it. Aly landed on the ground and hit her head on a rock. Shaking uncontrollably, Steffy crawled to her and called out, "Aly?" She threw the tire iron, and Ivy appeared. The paramedics arrived and Ivy and Steffy sobbed as the paramedic felt for a pulse and shook his head.
