It's not my fault Merlin looks like a girl, really.
And it's not my fault they don't look very much like themselves either.
Blame my crappy memory.
(One would think that after re-watching Merthur clips for so many times I should be able to remember EXACTLY how they look... Apparently, that's not how it works. :))
Or even better; it's...um, the dragon's fault! Yes! The dragon confused me with its talk about coins and destiny. Yes, that's it. ;)
