The new 'Game of Thrones' documentary shows the exact moment when Kit Harington realised what Jon Snow does to Daenerys on the finale

On Sunday night, HBO premiered a new two-hour long documentary called “The Last Watch,” which chronicles the making of the final season of “Game of Thrones.” Towards the start of the film, we see footage from the exact moment when Kit Harington (who plays Jon Snow) realised his character would kill Daenerys Targaryen.

The cast were sent all six episode scripts about three days before they came to Belfast, Northern Ireland, for a massive table read. But Kit Harington was one of the only actors who had chosen not to look at what was in store.

This means all of his co-stars were prepared for the shock of Jon slipping a dagger into Dany’s heart – but Kit Harington was stunned.

Harington pushed away from the table with his hand on his mouth right as cowriter and executive producer Bryan Cogman says, “We see Jon with his hand still on the hilt of the dagger he just lodged in Dany’s heart.”

He was sitting across the table from Emilia Clarke (Daenerys), who had already read the heartbreaking scene. She pulled some faces at Harington, while others around them looked both surprised or gleeful to see Harington’s real-time response.

Maisie Williams (Arya Stark) looks shocked too, so perhaps she didn’t read the scripts.

Jon Snow’s decision to kill Daenerys came after she burned the city of King’s Landing, ascending at last to the Iron Throne but making a troubling case for continued warfare in the process. The exact way in which Jon kills Daenerys, with a blade through her heart, was part of one of the biggest prophecies involved in George R.R. Martin’s original book series. You can read all about that prophecy and how it predicted Dany’s death here.
