[[caption-width-right:320:Then jump!]]

A StockPhrase usually used by characters believing in ThePowerOfTrust or ThePowerOfFriendship to save the day.

This usually goes down one of two ways. In the first, Bob and Alice are in danger. Bob has a plan, but needs Alice to trust him in order for it to work. Perhaps she needs to jump a ravine and trust that he will catch her. Or perhaps he needs her to act as a distraction for the BigBad and trust that he will take the BigBad down before she's in serious trouble. He will ask, "Do you trust me?" and if she says yes she will immediately need to prove her trust.

The second scenario is usually romantic with little to no real danger involved. Alice may be a little nervous of something, and Bob uses the question to reassure her. She may be wary of stepping out on a high balcony to look at the view or dancing in front of other people. The question may also be asked before TheirFirstTime. Be careful though, if the wording is "''Don't'' you trust me?", especially in a slightly pleading tone, it may be a sign that the person is at the best NotHimself and at the worst TheCasanova or TheVamp. That little apostrophe can make a lot of difference.

Common subversions will often either have Bob miss or Alice say that, no, she doesn't trust him. Sometimes they'll do it anyway.

This trope is about the truster confirming their faith in the trusted. Compare RememberThatYouTrustMe where the trusted reaffirms the faith of the truster.

'''Moss:''' No!\\
'''Roy:''' (angry) Moss!\\
'''Moss:''' I. Don't. Trust. You!
* Scully and Mulder say that to each other regularly on ''Series/TheXFiles'', though it became less and less frequent as the series progressed--not because they stopped trusting each other, but more like because their mutual trust reached almost telepathic levels.
* Subverted in the ''TwoAndAHalfMen'' episode "Walnuts and Demerol".
-->'''Evelyn:''' Do you trust me?\\

* The ''{{Chuck}}'' episode "Chuck vs. the First Kill"

* In the ''{{Smallville}}'' episode "Doomsday", Clark has just admitted to Jimmy that he's the Red-Blue Blur.

-->'''Clark:''' [Places the key into the pedestal and they are both surrounded by beams of light] It's okay.\\
'''Lana:''' [Looks around in amazement as Clark reaches out to her]\\
'''Clark:''' Do you trust me?\\
'''Lana:''' [Grabs Clark's hand and they are instantly transported to the Fortress of Solitude]
** The biggest one is probably in ''Collateral'', when [[spoiler:Chloe returns and asking Clark to trust her to escape from a virtual reality. He hesitates and loses the first chance, but he knows he still trusts her deep inside. It takes a darker turn when a bad guy assumed her likeness in the virtual world...]]
* The ''{{Dollhouse}}'' episode "The Target".

--->'''Amy''': But you don't always tell me the truth.
--->'''The Doctor''': If I always told you the truth, I wouldn't need you to trust me.
* [[Series/HouseOfCardsUK Francis Urquhart]] is fond of the phrase "You do trust me, don't you?". If he ever asks you it, ''run''.
* Sara asks Grissom this before starting to shave him in {{CSI}}.
* Angel asks Series/{{Buffy|the Vampire Slayer}} in "Lie to Me", "Do you love me?" before agreeing to reveal the truth about how he turned Drusilla into a vampire. Buffy replies, "I love you. I don't know if I trust you." (Angel replies, "[[{{Foreshadowing}} Maybe you shouldn't.]]") In Season 6 "Dead Things" Buffy is having a relationship with another vampire, Spike, but keeps [[ItDoesntMeanAnything insisting their relationship is purely sexual]] with no love involved. In response Spike [[KinkyCuffs offers her a pair of handcuffs]] and asks, "Do you trust me?" Buffy replies "Never" but the next day is seen [[CuffsOffRubWrists rubbing her wrists in a telling manner]].
* Series/{{Angel}} asks potential LoveInterest Detective Kate Lockley if she trusts him before handing over information on a SerialKiller without revealing the source. She says she does without hesitation, but later in the episode Kate discovers Angel is a vampire and she never fully trusts him again.
* A variation occurs in the BBC MiniSeries ''Series/TheSinkingOfTheLaconia''. Junior Officer Thomas Mortimer asks passenger Hilda Smith this, saying he only has four hours off-duty to do "whatever he likes". The set-up of the scene leads viewers to think he is making a sexual pass, but it turns out he's asking to be allowed to babysit her infant [[CrowningMomentOfHeartwarming so he can remind himself of his own children]].
* ''Series/GameOfThrones''. In "The Laws of Gods and Men" Tyrion Lannister is on trial with his father Lord Tywin as judge. It's a KangarooCourt with all the witnesses against him, so his brother Jaime makes a backroom deal with Tywin; if he pleads guilty and asks for mercy, Tyrion will be [[ReassignedToAntarctica sent to the Wall]] instead of being executed. In exchange Jaime will leave the Kingsguard (who are sworn not to take wives or inherit titles) and become Tywin's heir. Tyrion balks at this, as he knows his father hates him and the last person given such an offer had his head chopped off anyway. Rather than explain the bargain he's made Jaime says only, "Do you trust me?" [[BigBrotherWorship Tyrion just has time to nod]] before the trial recommences.
* ''Series/StarTrekVoyager''. In "Counterpoint" Inspector Kashyk uses this trope to justify the anti-telepath policies of the Devore Imperium. [[note]]The theme of trust becomes an important issue later when Kashyk claims he wants to defect to Voyager because he's turned against this policy.[[/note]]
-->'''Kashyk:''' Captain, do you trust me?
-->'''Janeway:''' ''(instantly)'' Not for a second.
-->'''Kashyk:''' Exactly, and why should you? Trust has to be earned. It's gradual, and yet it's the foundation of every relationship, professional and personal. It's also a concept alien to the telepathic races. Why take someone at their word when you can simply read their mind?
