It's 3 am, I must be lonely

Been watching some of my terrible (and so, unposted) Merlin vids, and found one where I specifically thought, amongst all the dragonblood/dragondaddy rumors from the end of series two, that Merlin would find out that he can control dragons and thus, also, Arthur Pendragon.

Feel free to point me to where this fic is, btw.
