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

...well i know that sonny with a chance finished a lot of time hace (maybe 1 año hace -.-") but i'm seeing again some episodes, most of all of the 2nd season (with Channy <3 XD). can tu 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 amor this series!!! and i've embed the video of the episode i'm talking about ;)
