Back to School - Bromance.Back to School: It is discovered that Dave failed his math test and did not graduate from high school, so he has to go back to school with the Chipmunks and Chipettes to take math lessons. However, lacking interest, he starts misbehaving with Alvin, until Simon and Theodore get fed up with it and give him the lessons themselves, leading him to improve and devising a strategy to help Alvin improve as well. With his good results, Dave takes the final exam and passes, finally becoming a high school graduate.
Bromance: Simon becomes friends with a new student, Jamie, with whom he shares interests. However, when Jamie realizes that the popular kid in their family is Alvin, he ditches Simon to hang out with Alvin. Simon is upset, but Alvin is not really digging Jamie either; besides, Jamie soon realizes that he does not have much fun around Alvin either, so he just ditches the Chipmunks entirely. In the end, Alvin tells Simon that Jamie is hypocritical and that it is his loss if he does not realize how cool Simon is.
