Here is another 'Merlin, Arthur' twist. If already known, then add it to the mix. Deals with the definition of a 'Dragon'.
Found: A 13th-Century Tale of Merlin and Arthur, Reused as Bookbinding
I am like most here in the US that were raised to believe that Merlin was a good guy and wanted to help Arthur, but after spending time here on Chrons and researching English, French and Norse Arthurian lore, I don't think the Merlin character was ever intended to be a good guy. Good in helping Arthur maybe, but with darker motives for his own gain.
I like the updated interpterion that
@Lafayette referenced, in that not everything is about sex. I just might want you to stop talking and/or asking questions! A very human felling that happens every day.
