i'm sorry guys, can te help me with an episode? thank you!!!

...well i know that sonny with a chance finished a lot of time fa (maybe 1 anno fa -.-") but i'm seeing again some episodes, most of all of the 2nd season (with Channy <3 XD). can te tell me if the episode in which sonny sings a song in a bar and she broke up with chad is the last one? on Youtube the episodes aren't always numbered, so i can't know if it's one of the lastest episodes... thank u anyway ;);)
P.S. i Amore this series!!! and i've embed the video of the episode i'm talking about ;)
