User blog comment:Adelina Le Morte March/It's NOT Arthur's Arm (also, a mistake I noticed on the diamond of the day page that needs fixing ASAP, except I don't know how)/@comment-5910167-20121230062044

Look at the arm! Look at the size of the wrist, the heavy build of the forearm and the lean musculature. I think some of you are simply incapable of judging the build of a man. Also note how HE holds the sword - the grip, the poise and the strength.

The dragon has just told Merlin to take comfort that Arthur that will return. Merlin throws the sword and Arthur's arm 'magically' catches it from the lake that Merlin must yet send his body into.

It is fairly straightforward and unambiguous.
