'The Young and the Restless' spoilers: Patty goes missing; Sharon's secret explodes

Time is running out for Sharon (Sharon Case) in "The Young and the Restless." The secret that she has been hiding for so long will finally explode in the episodes to come.

According to spoilers, things are looking worse for Sharon as people are getting closer to uncovering her secret. Patty went missing and she knows that her crazy friend is going to spill the beans if Patty doesn't find her. Nick (Joshua Morrow) is quite confused with her reaction though so she will try to calm down.

She will also find an excuse by saying that Patty is a dangerous person and she has always been scared of her even when she was in Fairview. Nick will be convinced but Sharon knows her time is up. Mariah (Camryn Grimes) will also start to panic and she will warn Sharon to tell the truth already about baby Sully before someone else does it for her.

Sharon will hesitate but her secret will explode unexpectedly. Celeb Dirty Laundry reveals that GC Buzz will be the one who will break the story to everyone. Nick will be furious once he will learn the news because all this time, his baby Christian is alive and Sharon knew about it.

Everyone will be stunned by the big secret. Nikki (Melody Scott) will even confront Sharon about concealing the truth from Nick. There's no word yet if Victor will chime in but things are expected to get complicated. Nick isn't even the real father as Sage (Kelly Sullivan) had an affair with Adam (Justin Hartley). That will be another explosion but for now, Nick will have to let this new fact sink in.

If they do a paternity test right away, the deeper secret is sure to surface soon. Will Nick find out that the child he thought was his is really his brother's? More of that will unfold on "The Young and the Restless" which airs Mondays to Fridays on CBS.
