Pay attention people - this one's likely to be a sudden-death round question in a pub quiz ten years from now.
While you entire being was engrossed in the blood, incest, borderline-dodgy acting and HODOR that makes Game of Thrones so spectacularly majestic, a sneaky little actor has pulled a fast one and you, taking not one but two roles in your favourite TV show. Didn't see it coming, did you.
**HEY, YOU, THIS IS WHERE THE SPOILERS BEGIN SO DON'T COME CRYING TO US IF WE RUIN THE WHOLE THING FOR YOU**
**SERIOUSLY, LOOK AWAY NOW IF YOU'RE GONNA GET ALL ANGRY ABOUT IT**
Crown-toting King Tommen Baratheon, son of Cersei and Jaime (gross) is played by a young thespian by the name of Dean-Charles Chapman.
You're right, he does look familiar. We're guessing you didn't see him in Simon Pegg's forgettable 2015 rom-com Man Up (of course you didn't), so where else could you possibly know him from?
Oh, only from that other character in the exact same show he's in right now.
Back before the psychologically damaging Red Wedding situation happened, you may remember meeting Martyn Lannister, Cersei, Jaime and Tyrion’s cousin (it's getting complicated, isn't it). He was the little lad who was taken prisoner by the House of Tully in season three, then offed by Lord Rickard Karstark in revenge for Jaime Lannister offing his own son. Still with us? Lovely.
Anyway, the point is, IT'S THE SAME ACTOR.
If you want to get really detailed about it, then know that Tommen and Martyn, in the big messed-up Lannister family tree, are first cousins once removed.
Got that? Cool. We can all go back to enjoying the guts, gore and frankly quite upsetting sex scenes now, can't we.
