ok i quit after page 3, but here's my newbie opinion. I've actually seen this and recently experienced it. i have a 'chemistry' with one of the dancers there, but it looks like a hot mess, but we get lost in the dance for that moment and have a great time. Then theres one of my instructors, it couldnt be more cold when we started. ice was warmer, we bumped into each other, tripped over each other. BUT as time has gone by with minor adjustments on both of our parts (mainly mine) we are moving much better and theres connection. Chemistry, what a tricky thing! put us in practice alone and its cold, stick us in front of people who are casually watching and we kick into performance 'show off' mode and you'd think we were life long friends about to get hitched. If you are looking to perform, give both of them a few test runs, people change in front of a crowd. That 'chemistry' might disappear. ALSO this chemistry...its it emotional? if so be VERY careful with that. I view dancing as a business deal, never mix business with pleasure or you will fall on your tail (most of the time).
