Season 3, Episode 4:

Reasonable Doubt

A former prosecutor who married a prominent criminal defense lawyer finds herself accused of murder and on the run after her husband falls overboard from their yacht.

Tropes present in this episode include

• Ambiguous Situation: Following the trend from seasons 1 and 2, the fourth episode of the season once again leaves the ending to our imagination.
• Asshole Victim:
  • Finch/Reese diverted the cops away from the POI by leading them to an underground gambling circle.
  • Reese grew tired of both POI's when they were both backstabbing liars and left them to their own devices, giving the husband a gun so that both of them could die.
• Batman Cold Open: The opening scene with Reese, Finch and Bear at the veterinary clinic.
• Call-Back:
  • Reese refers to himself as a "concerned third party".
  • The episode ends with a husband and wife who both want one another dead, just like in "Til Death". This time, Reese does leave the couple to their own devices.
• Cliffhanger Copout: Whatever happened after Finch found Hersh shot in the middle of the mental facility he'd put Root in?
• Continuity Nod: Nicole invites her friends to the book club using FriendCzar.
• Cut Apart: Team Machine hustle out Vanessa as it looks like the police are about to raid the safehouse, only for them to kick down the door of a gambling den Finch sent them to.
• Danger Takes A Back Seat: Reese again.
• Disproportionate Retribution:
  • Fusco has to restrain Shaw from stabbing someone who can't log into his own computer.
  • Detective Cameron wants Vanessa 'dead or alive', because of an old grudge.
• "Eureka!" Moment: Vanessa might have gotten away with killing her husband...except Carter finds the picture of him clawed and notes how she was doing it not when she found out he was alive or having an affair with her best friend but when she claimed she loved him.
  Carter: Most people think sweaty palms or an increased heart rate are the only involuntary signs your body gives when you lie. They're wrong.
• Faking the Dead
• He Is Not My Boyfriend: Averted; Laskey sees Reese talking to Carter and assumes she's moving on from Cal. Carter plays along with this. Then it turns out Laskey knew who the Man in the Suit is all along.
• It Seemed Like a Good Idea at the Time: Reese giving Vanessa his gun so she can protect herself.
• Leave Behind a Pistol: Albeit for a Mutual Kill instead of suicide.
• Meaningful Name:
  • The name of the yacht, Justice.
  • The name of the foundation: "Innocence Now."
• The Mole: Carter's partner, Mike Laskey, is revealed to be working for HR. Fans were not surprised.
• Mugged for Disguise: Vanessa knocks out her lawyer and takes her dress to leave the police station. In a rare, somewhat realistic moment for this trope, it's explained that she requested that lawyer in the first place specifically because the two women had similar heights, ages, and physical appearances.
• Only Bad Guys Call Their Lawyers: Played with; Finch is surprised that Vanessa doesn't call her lawyer during interrogation, only for her to do so after finding out what the evidence is against her.
• Prophecy Twist: The POI was framed for the murder of her husband, who was not actually dead because she was helping him fake his death so they could run off and start fresh, except he decided to double-cross her and set her up so that he could run off with his mistress (her best friend) and all of the money he had stolen from their charity, but then when the POI figured it all out she tracked him down, confronted him, and may or may not have killed him. Whew.
• Screw This, I'm Out of Here!: The POI and her husband tax Reese's patience and when he finds both of them have lied to him and deceived each other over their own selfish desires, he gives the husband a gun for him to try and kill his wife who's holding him at gunpoint and leaves them to deal with each other.
• Side Bet: Shaw wants to place bets on whether their number is the victim or the perpetrator.
• Spiking the Camera: Vanessa does this when buying a ticket at the bus station, tipping off Team Machine that it's a false trail.
• Subverted Catchphrase: When the vet asks the Who Are You? question, Finch replies that they're a couple of "concerned dog owners".
• That's What I Would Do: Reese notes with approval Vanessa's Framing the Guilty Party re the security guard who took a bribe to frame her.
• Trash Landing: Vanessa leaps off a building into a garbage truck to avoid a police dragnet.
• Whole-Plot Reference/Shout-Out: to The Fugitive.
• You Have to Believe Me!: Vanessa during Team Machine's 'trial'.
• You Remind Me of X: Vanessa reminds Reese of himself.
