So I saw this right and it's probably because amazing dancers just have incredible chemistry but it got me thinking.
(in my head Ghost is leading but it's up to your interpretation)
141 is a dance company, they have a few different styles :
Soap-swing, hip-hop, contemporary, doesn't have the patience or the timing for ballroom
Ghost-mainly ballroom, used to do swing but we'll get into that later
Gaz - swing, ballroom, contemporary, hip-hop, ballet, pretty much everything
Roach- ballroom, hip-hop, ballet, has tried others but only really likes dancing other styles with Soap and Gaz for fun
Price- ballroom, and Latin, has dabbled in almost everything but he prefers ballroom
Laswell- West Coast swing, you wouldn't think it but she is incredible she took home a championship title during an improv swing competition when she pulled her wife as a partner.
Nikolai- Nik dances ballroom, latin(only with Price), and Ballet, he was classically trained in St. Petersburg
Alejandro and Rudy- world titled Latin dancers(of course) but they also do ballroom and Alejandro does ballet while Rudy does contemporary, they both do swing as well when they need names on the ballot.
So: what if they're at an improv swing competition and Gaz goes down(Nik dropped him(that helicopter scene will haunt them in every universe)). In order to place in sweepstakes they need a full ballot and both Alejandro and Rudy(their usual backups) are already entered. Ghost is there for moral support and to make sure everyone gets filmed so they can look over it later, Soap is so so close to titling and he won't be able to if the team isn't complete(ik that's not how that works but for the plot). Ghost doesn't do swing anymore, not since an old partner in an old studio sabotaged him and almost ruined his career. But he can't say no to Soap, never could. So he puts his name in.
And as fate would have it.....
Out of a random draw of a hundred people Soap and Ghost get each other.
And this(the video) ensues, or something similar. And Ghost falls in love with swing again.
