As she paid homage to her ancestors in Sunday's episode, Sansa Stark made a surprising discovery in the crypts of Winterfell: a feather on the grave of her Aunt Lyanna. Where'd it come from? Think back.
"The last time we saw the statue of Lyanna was in the pilot episode," explains series co-creator David Benioff. "King Robert Baratheon laid this exotic, tropical bird feather in her hand. As we were preparing the scene [with Sansa], we thought: That feather’s probably still there. People haven't been going down there and cleaning up much. Certainly after Ramsay destroyed Winterfell, there hasn’t been a janitorial crew going down and vacuuming."
"We thought it would be kind of a great thing to have Sansa wondering about it," co-creator D.B. Weiss notes. "Hopefully viewers wonder: Where did I see that before? – and then remember that in the first episode of the show, this is something that Robert left to remember the woman he loved."
