Merlin finally returns for its second series on BBC One this Saturday, so to celebrate, we're declaring this week to be Merlin Week here on Tube Talk!

Every day for the next five days we'll be bringing you a different Merlin-themed interview or preview - and we kick off today by catching up with Katie McGrath (Morgana) and Angel Coulby (Gwen). Just how evil will Morgana get this series? And will Gwen start to develop feelings for Arthur? Click 'play' to find out!
