What is the Sonny With a Chance episode you think shes back about?

Answer 1

Mandy, an old cast member (Which was mentioned in Sketchy Beginnings) visits while on vacation. She starts to act like Sonny because the rest of the cast likes Sonny and doesn't like Mandy anymore and when she finds out Sonny replaced her, she steals the attention. Meanwhile, Sonny is walking around the studio to try to think everything out and runs into Chad, so they go to Sonny's dressing room and Sonny tells Chad what is happening, Chad feels bad for Sonny and comforts her. Tawni walks in on Sonny and Chad kissing (to her amazement).

19."I think she's back"

The former cast mate Mandy mentioned in a sketchy begining returns on vacation to the so random studio, revealing she is basically a clone of sonny acting almost exactly the same way she is. the whole cast of so random starts to ignore sonny and pay atention to Mandy fealing leftout she takes a walk through the studio and bumps in to chad, chad reasures sonny that she will not take her place and no one could ever do so and almost kiss until tawni enters.

these are the two answers i found hope it helps :)
