* ArtisticLicenseLaw: Contrary to how popular culture commonly portrays it, children cannot simply walk right into a high school without drawing attention. There is an entire process of joining the school all of which include records of past scholastic involvement. Children or Teens who appear out of thin air, princesses from the Middle Ages for example, would not be permitted to attend classes or dances.

* AmbiguousDisorder:
** In the pilot, Barry appears to have some difficulty with associating facial expression and internal emotion, which can be a sign of autism. This trait carries over in later episodes, so it is presumably an actual character trait and not a one-off joke.
** Marci probably also has … something wrong with her, though with her only appearing in two episode so far, it is difficult to tell what. Possibly ADHD.

* IveHeardOfThatWhatIsIt: Shelby does this in the episode "The Butterfly Effect".

* DidntThinkThisThrough: In "A Time To Double Date", Cyd and Shelby have conflicting events that they both want to go to together, so they use their time travel powers to both events. During both timelines, they meet guys that they're attracted to, but because only one timeline can exist, Cyd's meeting gets erased. [[spoiler: An attempt to fix this results in each girl falling for the opposite guy. They stick with those results afterwards]].

* ThirdPartyInterruptsAttack: Sebastian is about to kill a defenceless Shelby when Cyd picks up the sword lost earlier and blocks his swing. After being trounced mightily, Sebastian tries to stab Cyd in the back with a dagger and is knocked out by Shelby with a steel mug.

''Best Friends Whenever'' is a Disney Channel SitCom that premiered in June 2015. It follows best friends Shelby and Cyd, who develop the ability to perform MentalTimeTravel after being exposed to a science experiment gone wrong. It stars Lauren Taylor (on the left in the page image) as Shelby and Landry Bender as Cyd, both of whom are KidCom veterans (the {{Creator/Netflix}} / [=AwesomenessTV=] version of ''Richie Rich'' and ''Series/CrashAndBernstein'' respectively)[[note]]Both had also played the leads in a [=KidCom=] pilot for Disney Channel called ''Fairest of the Mall'' which wasn't picked up, but the network liked their chemistry so much they had them cast in this show[[/note]].

* BaitAndSwitch: Cyd asks Shelby if she "wanted to relive her first peer--", which causes Shelby to cut her off. Cyd then finishes by saying it was Shelby's first peer ''counseling'' session. It's subverted when it's revealed said counseling session was [[GettingCrapPastTheRadar about Shelby's period]].

* NoPeriodsPeriod: Averted in "A Time to Jump and Jam". May be the first show in Disney Channel history to actually mention periods. In a subverted BaitAndSwitch, no less, where Cyd asks Shelby if she "wanted to relive her first peer--", which causes Shelby to cut her off. Cyd then finishes by saying it was Shelby's first peer ''counseling'' session. It's subverted when it's revealed said counseling session was [[GettingCrapPastTheRadar about Shelby's period]].

* ObliviousToHisOwnDescription: In "When Shelby Net Cyd", Naldo is unaware that Shelby is referring to him when she talks about Cyd's fourth grade crush, including his love of wearing hats and Cyd ounching him in the arm to shush him.

The show crossed over with both ''Series/LivAndMaddie'' and ''Series/GirlMeetsWorld'' for each series' HalloweenEpisode in October 2015. This inducted the show into the Franchise/{{DCLAU}}.
