I think a reason why Sam and Freddie broke up (if they have definitely broken up) is because, if Seddie carried on, it would just be the same all the time.
(All this next paragraph is what I’ve seen Seddiers tweet on twitter).
Sam and Freddie would be dating and in love, and that’s it. There wouldn’t be any major insults or physical arguments 24/7 or anything, it would seem a bit, boring.
I think Dan is just trying to make the season more new (but old at the same time with Sam and Freddie being just ‘friends’ again), and exciting, with a WHOLE LOAD of twists along the way. I think Sam and Freddie will get back together, and that’s why they said, I Love You AFTER they decided on breaking up. There is still a future for Seddie, I just know it.
Also, many people have been saying how iCarly isn’t the same anymore or how it used to be, and that’s another big reason why Dan has done this to us. He’s probably trying to get the iCarly season back to how it used to be, and then gradually, Seddie will hopefully come back again. :’)
Dan knows what he is doing, he wouldn’t just upset us like that. Sure, he broke up Creddie and has never mentioned it again, but Seddie definitely had something more to it. Sam LOVES Freddie. Carly didn’t.
So let’s try to stay positive and just enjoy the rest of the NEW Season! :D
