It's revealed that Kendall likes skateboarding.
Big Time Break-Up and Big Time Single can be combined into a one-hour long special. Big Time Break-Up alone already counts as a special.
Big Time Single is the 21st episode of Season 2 of Big Time Rush and the 41st episode overall. It aired on July 23 2011. This could be Big Time Break-Up Part 2.
