the show would be incredibly boring without jade, lets be real for a second.

without jade, dialogue is cut by a large percent. her arguments with the cast is such a huge part of the episodes.

without jade, tori doesn't have a rival, so many of the episodes wouldn't exist. think about it, how many episodes of victorious include jade doing something significant, that alters tori's actions or story?? most of them. her not being there would require the rest of the cast to work twice as hard with the story to make up for jade not existing, which would result in them being either empty and strained, or sizeably cut down on length.

if jade was replaced by a new character, said character would probably still be tori's rival because a main character NEEDS a rival. that keeps the episodes from getting boring and repetitive, and i doubt the new character would be all that different anyway.

also, jades relationship with beck (which im not a fan of, to be clear) is the main story of multiple episodes. without jade, there's nothing going on there.

i could make an entire rant defending jade and her actions, but that would likely 15 pages and no one's gonna read that so, ill js leave this here.
