Dan would have had some one time character declaring her love for Freddie and Carly get jealous of that.
Dan would not use Sam in that fashion. Sam is not a punching bag that is going to be tossed around by Dan.
Dan loves all of his Characters. The show is on Nickelodeon. It's core audience is for ages 9-14.
Each Character is going to get a happy ending. Ask yourself the following questions based on what we know from the 4 plus years iCarly has been on.
1. Can Sam Puckett have a happy ending if she doesnt end up with Freddie? From what we have seen, The answer is no.
2. Can Carly Shay have a happy ending if she doesnt end up with Freddie? From what we have seen, The answer is yes.
People assume if forget and don't acknowledge Freddie in my arguments. I do. I have said many time he doesnt have to reciporcate feelings for Sam.
The point of this blog is to say.....If Dan was going to have Carly with feelings for Freddie. He would not have spent four years building up and having Sam Puckett declaring her love for Freddie.
