my speculation for this I heard carly and tori fight over a guy in this episode and sam and tori duet. i think when sam sings she gets invited to join hollywood arts. and Sam:says: ill have to think about it. tori gives sam her number say txt me whenever ur in La and we could meet up. they goto La for Peoples Choice Awards for best webshow in USA and sam gets a tour of the school and when no ones around on the stage she sings not that far away. but the principle sees it and offers her a scholarship and sam takes it.
