Warning: Contains spoilers for Game of Thrones Season 6.

"When you play the game of thrones, you win or you die." Except for one very lucky actor who's done both, just in separate roles.

Dean-Charles Chapman is currently known on Game of Thrones for playing King Tommen Baratheon, first of his name and however it goes, who took the throne in Season 4 after his brother Joffrey's death. But Chapman has only played Tommen since 2014, because the character was recast from the much younger actor, Callum Wharry.

But oddly, Chapman was in the show before then, by the name of a tiny lordling named Martyn Lannister. Hello Giggles first caught the similarities, noticing that the the king who's "only half-Lannister" looks exactly like his pure-blooded Lannister cousin (and also, IMDb says so).

For reference, that's Tommen on the left and Martyn on the right:

It's an easy thing to miss because poor Martyn Lannister only appeared for two episodes in the third season before getting the axe. For those who remember way back when Robb Stark had an army and was alive, Martyn and Willem Lannister were taken as hostages by Robb's army.

But in a fit of vengeance, they were murdered by a northern lord named Rickard Karstark. Robb, channeling his inner Ned, was furious over the murdered children and beheaded Karstark himself. Karstark's son is still bitter toward Starks in Season 6, and now works for Ramsay Bolton.

While this likely has no effect on the greater story, it does feed directly into the never-discussed "Tommen is a faceless man" theory. That is probably nonsense, but that's never stopped Game of Thrones theories before.
