Melanie didn't pretend to be the primal twin, Sam did.Maybe Melanie agreed to help Sam with her "evil twin" plot, but I doubt Melanie would be willing to go so far as to pretend to be a crazy person in the middle of a crowded restaurant. So Melanie posed as Sam while Sam pretended to be her own crazy evil twin. Hey, this wouldn't be the first time the fandom suspected Sam of pretending to be Melanie to kiss a possible love interest.

"Sam & Cat" is a Show Within A Show.In #Blooper Episode, the characters refer to each other by the actors' names (Ariana, Cameron), and Sam/Jennette point out that Goomer is not a main characer of the show.

After the last episode, Sam and Cat have a falling out.Sam did let Cat get arrested and sent to jail for two weeks. It would be hard for Cat to forgive Sam for doing something like that to her.
