User blog comment:Aithusa07/List of Plotholes from Merlin/@comment-4623180-20120209090008

For 1, it doesn't really matter, Morgause is dead and now and will probably only be mentioned briefly a few short times, if at all. It doesn't matter if they were blood-related, they still treated each other like sisters (with Morgause using a hint of manipulation). As for 2, the character of Julius Borden was an idiot so it doesn't really matter. 3, mmm, I don't find it annoying but just remember it's a show and they don't care about these kinds of things. I'm surprised you haven't mentioned "how the hell does Morgana get time to do her facial makeup, and manage to dye her hair green and use dreadlocks?" Yet she lived in a hut and we never saw a mirror in there. But we allow this is to happen because it's the magic of the show and we love it! As Gwainered said below, they probably do use blades to cut themselves, I'm sure there are methods. Gaius has loads of potions that could stunt hair growth, as well. I do hope to a see a more bearded Merlin soon, though, simply so he can fit that model of the old, wise advisor. Aithusa helping Morgana, it was MEANT to be a twist. I don't think it's a hole. It'll all be explained soon.

Every show has its hole, every show is nothing like in real life, so just enjoy!! :) Good thread, anyway.
