The bombshell dropped of who has been working with Marco (Peter Bergman) during Wednesday's episode of The Young and the Restless, which is truly shocking since Detective Harding (Chris L. McKenna) is supposed to be on the side of good instead of evil.

Why Is 'The Young and the Restless' Cast 'Getting Fancy' While On Their CBS Set?

Marco is hellbent on reclaiming Jack's (also portrayed by Bergman) life and he expects Detective Harding to do whatever it takes to make that happen even if that means the body count in Genoa City grows a bit more.

In the episode airing today, Aug. 13, Marco threatens Detective Harding, telling him, "You will handle our problem or you're the one that's going to be erased," as seen in the sneak peek below.

Flashbacks Will Reveal Who Killed Austin & Courtney On 'The Young and the Restless'

According to Soaps, Summer (Hunter King) will have an eye-opening moment, which will make her realize Austin (Matthew Atkinson) died at the hands of Detective Harding.

Summer will wake up from a nightmare that took her back to the night at Abbott cabin when Austin was killed and she will seem to have remembered hearing music, but won't realize its significance until she's in the park with Detective Harding and his cellphone's ringtone goes off. His ringtone is the music she recalls, but why would he have been at the cabin? It's all going to click that he is responsible for killing Austin.

That aside, Colin (Tristan Rogers) is blackmailing Devon (Bryton James) as seen in the sneak peek. He's relentless and gives Devon an ultimatum of either coming clean to Hilary (Mishael Morgan) on his own right away or Colin will do it.
