how do you know that she is the seventh element?

I read somewhere

I just don't want her to be main 7. I mean she still has a Cutiemark that shows her erasing cutie marks. That's her talent so... How would you know she changed?

she might have a talent that isn't necessarily good, but that doesn't define her. she might have a talent that can do bad but that doesn't mean she will use it, that just goes to show how much she has changed and that she has changed! she has the power to do bad in fact, it's her special talent! but she isn't using it anymore even though she can. she definitely has changed.

her talent isn't good not, necessarily not good.

and her cutie mark doesn't really look like it represents taking cutie marks

grr I do not want 7 elements it's just not right!

and, how would they make a seventh element, they would have to make a huge backstory for that

I know ^^
