User blog comment:KALegend./How powerful is Mordred?/@comment-1509826-20121222211621

What do you mean his powers haven't grown? He knocked Morgana out cold with a single non-verbal spell in "With all my Heart", merlin only  just learnt how to do that this season. It was stated he could kill atleast for people at once in the "the drawing of Darkness" In the most recent episode he and morgana were able to conjour a giant ball of fire during the siege.

Evidently he has got more powerful, he mearly prefers not to use his abilities, perhaphs his constant running turned him against them, or perhaphs he just wants to be a warrior, but he definatly has them.
