I think Ryan has a secret (or not-so-secret?) Man-Crush on Kris.
Ryan always has a mancrush on someone every year, even just so he can make Simon jealous with all the fist-bumps and high fives that Simon probably detests.
Season 4 had the rockers on board while 5 had Ace. Season 6 had Chris and whenever Blake had a moment, you could see Ryan cream. Season 7 was the Davids, one to meet your parents before prom while the other you meet behind the bleachers after his set playing in the prom.
