After losing Arthur, Merlin semi-accidentally travels back in time. In an attempt to change the future, Merlin takes Morgana under his wing and trains her in magic, all the while trying to pretend he's not still in love with an Arthur who doesn't remember that they used to be married (in the future, that is), keeping an eye out for Morgause, and juggling Camelot's run of the mill crises. You know, the usual manservant stuff.
