Seriously you guys, I would not even take this "Gibby trying to break them up" seriously! I mean, it's GIBBY! :lol: I'm 99 percent certain it's Mrs. Benson bribing him (yellow fruit! ) to do some digging and work for her to see what's up. It'll be mainly for comedic purposes.
It would be hilarious! And we all know Sam is insecure when it comes to Melanie, so having her there all of a sudden, and Freddie realizing she is real and Sam let him 'win' back then could make for some interesting moments between Sam and Freddie. And Melanie is everything that Sam is not, she's more the girly girl like Carly. Perhaps it would open Freddie's eyes all the more just what it all is that he loves about Sam, why he wants to be with Sam more than any other girl.
