User blog comment:Aithusa07/List of Plotholes from Merlin/@comment-123.2.187.141-20150513150005

I always thought the biggest plot hole of the entire story was Kilgarrah... He says Uther killed all the other dragons but how exactly? A dragon lord wouldn't have been able to help him otherwise he'd have had no need for Balinor. And we all saw how much havoc, ONE dragon can cause when Kilgarrah attacked.. are we supposed to believe all the dragons noticed that Uther was hunting them and just decided to not bother?

And lastly, we've seen Merlin battle all kinds of sorceres over the years. Powerful, determined sorcerers. We've also seen the pitiful attempts the knights of Camelot make to kill these sorcerers. So once again we're expected to believe that a whole nation of people simply sat idle and did nothing to defend themselves while Uther sent out his rather incompedent knights to hunt them down and lead them to the pyre?
