Argh, I can't give you a conclusive answer to that one. I lean more toward Merlin NOT going back to Camelot because it would just rub salt in his already enormous wound. You made me lol so hard at what you said about Leon thought, because I completely agree.

I do think Gaius would journey to the lake to say his goodbye to Merlin, because he knows exactly where he would be. Oh, Merlin! I can see him living in a hut near the lake, just wiling away his days while he waits. *sigh*
