King Tommen Baratheon, first of his name, King of the Andals and the First Men and Protector of the Realm (and, if you ask us, soon to be deceased) hasn't had a lot to do since he came to sit on the Iron Throne apart from simper away as Cersei and Margaery, and now The High Sparrow, fight his loyalty and attention but it turns out that the actor who plays him has a lot more experience than he's letting on.
Dean-Charles Chapman joined the show as Tommen in season four, but it turns out (thanks to the work of eagle-eyed viewers) that he was already very familiar with Westeros. Why? Because he popped up in season three as his very own cousin.
Yes, that right there is Martyn Lannister, son of Kevan Lannister and first cousin once removed of Tommen, played by the very same Dean-Charles Chapman. We knew the Lannisters were mostly blonde and looked alike but this is getting ridiculous.
Now if you'll rememeber correctly, Martyn and his brother Willem were captured by Robb Stark's forces and were to be used as leverage against the Lannisters but then Jaime killed Lord Rickard Karstark's son, and Lord Rickard then killed the two brothers, for which Robb Stark killed him and led to the Karstark's betraying of Robb at the Red Wedding and, look, it's a long series of mistakes and we all know how it ends. The main takeaway here is that you can almost blame Tommen's clone-cousin for it all. But it also frees up Chapman from having to worry about having to do any greenscreen work where he has to act with himself.
Not that he should be worried about working on the show much longer because, as we said, Tommen's days are probably numbered.
