Spoiler alerts for ”The Young and the Restless” tease that Ashley is about to drop a bombshell on her older sibling. She will tell Jack that he can stop looking for his biological father because she knows his identity. It's possible that Dina was mistaken and John Abbott is Jack’s father after all.

Ashley may have paid Andrew, the lab tech, to alter the DNA test results to get even with her brother because he invoked the Blood Abbot Clause at Jabot. This would indicate that Dina’s daughter is as vindictive as her ex-husband Victor as she inflicted months unnecessary suffering onto Jack.

This revelation may also pave the way for Eileen Davidson to exit Genoa City once the truth is revealed.

Ashley may have paid Andrew to change test result

Soap Dirt spoilers suggest Ashley was so infuriated that Jack used the Blood Abbot Clause against her that she sought the ultimate revenge. She may have taken advantage of her mother’s faulty memory, due to Alzheimer’s and hit her sibling where it hurts the most. It's possible Ashley paid the lab tech to lie about the DNA results and spoiler alerts from Celeb Dirty Laundry indicate this decision may come back to bite her.

CDL suggests that if Ashley paid Andrew to give her sibling fake test results, Jack will feel betrayed. This is the type of move that he would expect from Victor but not his sister.

On Monday, Ashley was officially named CEO of Jabot and her brother congratulated her. If it turns out she bribed Andrew to deceive her sibling, meaning she will more than likely lose her new position. The scandal would be an ideal reason for Ashley to leave Genoa City.

Jack will finally get the truth about his father

Previews for Tuesday's episode of ”The Young and the Restless” show an irate Jack asking his sister why she is writing checks to Andrew.

Ashley screams that she will tell her brother the truth. If spoilers are correct, Jack will find out that the lab tech was paid to give him false information and that he is indeed a Blood Abbot and John is his father.

Ashley has stood by for months, watching the torment her older sibling has endured while trying to locate his biological father: Kyle took a bone for a DNA sample from Phillip Chancellor's grave, and Matt Miller was called to convince Bicyor to submit to genetic testing.

If Jack finds out that his sister sent him on a wild goose chance things will become ugly very quickly.

This bombshell revelation is going to have long lasting results so stay tuned in for all the action. Be on the lookout for updated spoilers as Eileen Davidson’s final days in Genoa City draw near. ”The Young and the Restless.” airs weekday afternoons on CBS at 12:30 PM EST on CBS.
