Just then, a raven delivers a message from Cersei Lannister, and Jon casually ignores her threats.
When this happens, Sansa warns Jon:
“You’re the military man, but I know her. If you’re her enemy, she’ll never stop until she’s destroyed you. Everyone who’s ever crossed her she’s found a way to murder.”
“You almost sound as if you admire her,” replies Jon.
“I learned a great deal from her,” she says.
That’s when people noticed an unsettling detail: Sansa is rocking Cersei’s hairdo.
