Episode 7 of "Shark"
s01e07 Déjà Vu All Over Again

Sebastian hopes that his current case of a murdered 8-year-old girl will result in the exoneration of his former client, whom Jessica helped convict for a strikingly similar murder 15 years ago. Jessica, who is convinced the correct man is behind bars for the previous murder, warns Sebastian not to let his loss to her in the old case cloud his judgment on the current one. However, Sebastian quietly assigns Raina to pull information on the former case and asks his imprisoned former client, Charlie, if he can connect any of the current suspects to the past crime. Meanwhile, Julie is shocked to learn from an outside source (Bryan) that her mother may not have been faithful to Sebastian during their marriage.
