"How could you?!"

That’s what millions of Game of Thrones viewers (and wise readers) were thinking this spring, back when Olly, the sweet summer child of the Night’s Watch, stabbed Jon Snow in the back gut in the show’s season 5 finale.

But in a new interview with Express, actor Brenock O’Connor says he’s “happy with the reaction” garnered by the traumatic moment — and that the scene was “great fun to film.”

O’Connor adds that he was in the dark about the shocking twist, but we all know that Olly was probably plotting mutiny for awhile. The actor isn't sure whether his character will return in season 6, but you know who won’t? JON SNOW. (Maybe. Actually, maybe not.)
