SUPER FUCKING LATE ON THIS, I might've been out of commission for a while but I figured I'd drop by with a word! Morpheus would know him, obviously, because he's Merlin's best friend and Merlin is pretty much his keeper, maid, life partner etc etc. Morpheus probably isn't too impressed by him, but then again he's rarely impressed by anything! He's really sarcastic and usually acts very bored but it's easy to get on his nerves and annoy him, so DO WITH THAT WHAT YOU WILL.
