They quickly realized Graham was up to no good and was likely making plans to kill their mother, but the Abbott sibling's saga with their enemy will take yet another unexpected turn on the Thursday, Jan. 18 episode of "The Young and the Restless."

Jack (Peter Bergman) and Ashley (Eileen Davidson), after discussing the break in at the Jabot lab, realized that the compound that was still missing was potentially fatal if injected, and Ashley remembered that Graham (Max Shippee) was in possession of a syringe. Realizing he intended to kill Dina (Marla Adams) on the CBS soap, the two siblings quickly raced to their hotel room to try and stop him. However, they will be shocked by the scene that they find instead.

Dina will be gone, and Graham will be on the floor, with the syringe stuck in his own arm. Though they would love nothing more than for Graham to die, the siblings will quickly take action to get him help at the hospital, and they will then try to figure out where their mother has gotten to now, befor she gets into trouble again.

Young and the Restless
Ashley (Eileen Davidson) is stunned after Paul (Doug Davidson) makes a shocking accusation against her on the Jan. 18, 2018 episode of "The Young and the Restless." CBS

However, things will go unexpectedly, as they quickly learn their mother is at the police station, where she turned herself in to Paul (Doug Davidson), and indicated she had murdered Brent Davis. However, her Alzheimer's diagnosis, and the fact that she is currently living in her own past most of the time, will keep her from facing any charges. Instead, Ashley will be stunned when Paul informs her he actually has questions for her about what happened to Graham, as her fingerprints are on the syringe that was in his arm.

Ashley will be floored that Paul seems to think she may have attacked Graham, especially since the compound was one stolen from her own lab. She will also reveal that Graham was attempting to set her up, as he had invited her over to the hotel suite for an alleged lunch, and asked her to grab the syringe for him because he needed it in order to give himself insulin for diabetes.

Despite her denials though, she could wind up in bigger trouble than she realized later on—as Graham likely won't make it and will die from the injection (which he received after a struggle with Dina). If he does die, Ashley may find herself in some serious hot water.

"The Young and the Restless" airs weekdays at 12:30 p.m. EST on CBS.
