Vampire Diaries - Adding two female regulars to the cast

"There's plenty of characters coming but the couple of regular characters that we're bringing in are female, so I guess they could be lesbians but we're bringing them in for love interests. Once the wheels are in motion, it's hard just to add something simply because you want to do it."

Any Guesses who the new characters may be? Meredith perhaps?
