She was being cocky and rude on set, but that wasn't the main reason she left. It was mainly her decision to leave. She thought she could make it in film. To tell toi the truth I think the montrer got better after she left. Tiffany Amber Thiesssen came in as Valerie and was pretty much Brenda's replacement(to fill the void) and she was a perfect replacement at that. She added an edgier and plus mature link that tremendously improved the cast. Brenda was pretty one dimentional. toi never knew what toi were gonna get with Valerie. The écriture also got better. It is really cool to see how the jouer la comédie and écriture got better and better as the montrer progessed.
Okay the character Brenda they wrote her off the montrer to live in Londres and further her jouer la comédie career, (she tells Dylan to wait for her &she wont be gone forever and she doesnt come back) But from what i have watched of interviews and read in mags livres and ect. They let her go bc she couldn't get along with eny of her cast mates off the camera. Im not saying that that is a 100% true but it is what i have seen on some interviews and read in mags livres and ect.
