Will (E.?) Shields/Castleview

Has anyone thought of a good middle name for Will Shields from Castelview? I at first thought that Everyman would be an acceptable one given the ubiquitous nature of arthur's descendants, but when I read the final section I couldn't help but think that perhaps it was Excalibur. Both sides want to employ Shields as a weapon, and he floats with the scabbard in the final scene. Both a shield and Excalibur are wielded, and Will returns to the Lady of the Lake just as the sword of legend does. Any thoughts on this? Obviously there doesn't seem to be any one definitive answer in the text. Marc Aramini
