Memorabilia

"This is the solution to all our problems. Allez, les amis. We must go. Madames et monsieurs, may I present to you, La Machine à Mémoire, or as they say in Amérique, you know... The Memory Machine. Oui, Iris. Memory Machine. Many times... I have entered into people's minds using this very technology."

- Sherloque Wells and Iris West-Allen

Synopsis
When Sherloque wants to use a memory machine on Barry and Nora to help gain access to Grace's memories, Nora panics, fearing her parents will find out the secrets she's been keeping from them. Nora secretly decides to use the machine on her own, which ends in disaster after she gets trapped inside Grace's mind. Barry and Iris go in after their daughter and Iris is brokenhearted by what she finds. Meanwhile, Ralph tricks Cisco into going out for a night out on the town.
