Oh wow, Cassie's back. The most aloof of the original Skins is now spending some time alone in London, trying to make sense of her life. However, it isn't long before she realises that she isn't on her own at all, because someone has been secretly following her. A bit of an odd friendship blossoms from mutual loneliness but, much like everything else in Cassie's rather odd life, she's not sure it can survive in the real world. Wow. We've rather liked seeing Hannah Murray on Game of Thrones instead...
