Game of Thrones actor Pedro Pascal has shared a friendly picture of himself and co-star Hafthor Julius Bjornsson on set following the battle between their characters Prince Oberyn and The Mountain.

Pascal (Oberyn) posted an Instagram picture of the pair with the caption "buds", in reference to their fight in Season 4, Episode 8 – The Mountain and the Viper.

Bjornsson is shown striking a wrestling pose, while Pascal stands next to him doing a thumbs up.

In the episode, Oberyn and The Mountain fight to the death, with a particularly bloody end for Pascal's character.

Unbeknownst to fans of the show, the eye-gouging death was hinted at by co-star Lena Headey (Cersei Lannister).

In an Instagram picture from April, she is pictured with Pascal pushing her thumbs into his eyeballs.

After the show aired, viewers quickly latched onto the reference: "this totally makes sense now," one wrote. Another added: "I would have never have guessed."
