Magic Blade
He remembered Excalibur hanging like a normal sword from Arthur's belt, springing into action only when the King wielded it, nothing more than a normal blade then.
Whenever Excalibur and Jenkins happened to run into each other (or whatever one might call their meetings), the sword soared away from the former knight as quickly as possible, like it was hiding something.
But maybe, Jenkins mused, it was something different. Maybe Excalibur was feeling guilty about not being able to defend the King against its evil twin, Clarent – or maybe the magic blade missed Arthur just as much as Galahad did.
A/N: Researching for my Merlin fanfiction I found a name for Mordred's sword: Clarent, originally one of the Arthur's own swords, later abused by his son to kill him (depending on which legend one builds one's story).
I'm so happy Excalibur is back on the show! Really missed the sword!
Though I really have no idea why people thought creating a sword moving on its own accord, displaying emotions and causing wounds that cannot be healed was a good idea. Imagine what would happen if it experienced a mid-life crisis... Well, just a thought.
