Just chiming in with this is why I have worries when I do OOMs or just Will sometimes. I know his character really well, but he's also clearly a part of the Robin Hood legend which is large and many headed.

He's just my interpretation of one part of it but considering that certain ideas about RH make me twitch, I always worry that somehow my Will might be doing the same for other people and then I feel bad. So I understand completely even though he doesn't have the mystical issues, he's still very much a huge public domain character.
