Nick and Norah are united by a very unique love of sounds, so it's appropriate that we turn to Numerology (and the mathematical vibration of their names) to understand how compatible they are.

Nick's Dominant Impression Number is 5, and 5s are true survivors. This explains Nick's ability to perform onstage even after his shattering breakup (and even when his ex shows up with her new squeeze!). As Nick gets sucked deeper and deeper into a crazy night, his typical 5 instincts serve him well. 5s can appear to make impulsive decisions, but it's only that they have such sharp instincts, so their judgment is quick and accurate.

Meanwhile, Norah's Dominant Impression Number is 2 -- a number known for promoting security and diplomacy. Norah's main focus for the night is getting her best (and very drunk) friend Caroline home safely; this throws her in the path of Nick, and Norah realizes she already knows him -- not personally, but by the mixtapes he made his ex-girlfriend. As a 2, Norah is already very passionate, so her attachment to Nick through his music is very strong.

These two make an excellent team: Nick's quick 5 reflexes and Norah's 2 ability to avoid dangerous situations means that they can navigate their way through a treacherous night. And Nick's quiet attraction to adventure, and Norah's passion, means that their bond might be something more than a friendship of convenience.
