TinkerbellClap: Nigel Wright.
Just kidding kii, I would say... Wren is just too easy and too obvious, all the girls said their jaw dropped when they knew who Charles was. I don't think it's Cece because in EP9 it didn't seem as though it was a girl that's pushing Ali. In the promo it seems as if Charles is really related to Ali, so I'm just going to go with Wren.
It's too simple for Charles to be Wren, but then again it's Marlene so.
I guess.
