We don't know if this is the last season or not. It hasn't been renewed yet, and they still have to film Victorious and the second half of this season. I disagree, I think this is one of my favorite seasons so far. I think something about it is making it a little more mature. I'm not sure what it is...maybe the actors?? I like it better, and many others do too. I don't think they have reached their peak yet, to be honest. There is a lot of character development that can be done.
@Lampy: Sam has never intentionally harmed Spencer or Carly for as long as she's known them. It was in character of her to never hurt Spencer. She also hasn't physically hurt Freddie or Gibby in a long time(we always exclude iSpace Out due to OOCness from the space madness) so she is sort of maturing. Sort of...
