14. Wizard Of Oz

This being a musical episode, and producer/writer Andrew Kreisberg being a particularly big fan of musicals, there are inevitably a lot of shout-outs to famous musicals, and one that gets a lot of love is The Wizard of Oz.

As it transpires, this is the movie Kara used to watch all the time growing up, so of course it's directly named-checked, as well as a couple of other nods throughout the episode. Kara sarcastically mentions that she can just click her heels three times to take them home, and hopefully answers that all they have to do is follow the yellow brick road.

Plus, the way Kara and Barry first meet in this world, without any idea of what is really going on, is a definite "we're not in Kansas anymore" moment.
