I also dislike her attitudes after she is being too much selfish than the others, another reason she is being dishonest to her friends.
Brandon is not one of my favorite characters in Winx Club, as he saved Stella for some reason.
Shouldn't she only cares about herself or too much pampered or spoiled brat?!? Yeah, no.
Too much ego for a character is not a good idea that Iginio Straffi making or the other director.
She might thinking her friends is okay, but her selfishness is annoying me.
Why did Italian directors made such a selfish character like Stella?!?
