Perverted bisexual Russian? Eh, go on. Nikolaj is going to be hilarious to play, he's a little bit of a womanizer himself. It's more of his wit, and his charm that sort of works it out. Hence why he may be known as "Jamie fooking Lannister" for not just his appearance, but perhaps his actions, a kind of comedic relief in his character I would say. Merlin is too beardy for love. But his beard=love.
