Yep I've heard that rumour as well... Why does Gwen wear that black dress, when all of her dresses are either purple, blue, pink or red.

Also in the trailer (the Dark Tower), Gwen says that she wants no part in Morgana's plan (so that's why Morgana enchants her). I also saw a mandrake root in the Series 5 trailer and Gwen screaming under it. So maybe Gwen loses her mind and maybe Merlin has to fix her?
