The Young and the Restless has been hinting that Summer (Hunter King) has been suppressing memories from the night Austin (Matthew Atkinson) was killed and it seems as though those memories are finally coming back to life!

'The Young and the Restless' Got Actress Mishael Morgan A Body Double, But Why?

Summer recently recalled a musical tune she heard while at the cabin. When she heard Detective Harding's (Chris L. McKenna) ringtone it clicked even more to her that was the same thing she heard at the cabin.

During the episode of the soap airing today, Aug. 20, Summer will finally piece it all together and conclude Detective Harding was in the cabin with them. In the sneak peek below, she frantically tells Noah (Robert Adamson), Mariah (Camryn Grimes) and Kevin (Greg Rikaart) that she really did recall seeing Detective Harding at the cabin that night.

Jack & Marco Will Come Face-To-Face On 'The Young and the Restless'?

"Guys, I remembered! I did see someone at the cabin the night of the murder," she rushes out, adding, "I saw Harding."

This revelation will prompt many questions from Dylan (Steve Burton) later on in the episode, according to Soaps.

Plus, Noah will take matters into his own hands in terms of confronting Detective Harding since he wants justice for Courtney (Kelli Goss).

Dylan will also question Victor (Eric Braeden) about Marco (Peter Bergman) as seen in the sneak peek clip below.

Plus, will Jack (also portrayed by Bergman) end Marco the way Marco wants to end him? In the sneak peek, Marco pushes Jack's buttons and Jack smashes a bottle on the mantle and looks like he will slice up Marco's face with it.

"Go ahead! Do it!" Marco even shouts at Jack.

All of the doppelganger storylines aside, Hilary (Mishael Morgan) will be in a bad place. Police will notify Devon (Bryton Hamilton) that something happened to her on the trail according to Soaps.

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