Haha, yeah, Merlin was so into that conversation that he's actually the one that starts it! :P

That sounds like a fun project with your fanfic writing friend! :) I think Merlin is actually a really good show for writing about, because there are noticeable deficiencies in the emotional-plotting of the show. So, basically, you don't mind the "missing scene" genre of writing, you could have a field-day...or do what I do, and stick in your "missing scenes" into plotty fics.

Anyway, I hope it works out!
