I was so mad at Merlin in S4E12 because after all what Gwen went through to warn him about Morgana’s next attack on Camelot; he didn’t manage to even keep an eye on uncle Aggy let alone use his power to prevent it from happening and they were all taken by surprise. I know I should be mad at the writers, though.
I floved this cut where Arthur looked over and saw Morgana and her posse storming through like serious bamfs.
