Yeah, I was quite bothered by the way Morgana got shoved out of the main action all season. If you're going to have a character who was such a stalwart voice for doing the right thing and but her on a path toward evil, you should really show that character doing something other than watching duels. :(

Merlin really needs to learn some spells to make himself invisible so he can do undetected magic without straining our credibility quite so much. Spells to heal head trauma would also come in useful.
