When the blade is in his pale neck, as she watches the blood spill across her skirts, as she watches him convulse, the mockingbird calls her Catelyn.
She doesn't think Catelyn would have held the knife, watched him struggle, and felt happy.
After they slaughter the Freys and take the twins the corpse called Lady Stoneheart comes to her and strokes her hair with a rotting hand.
What's left of her mother tells her she looks like Robb.
No, she knows she is not like Robb.
Robb would have never used something as dishonorable as poison, Robb would never have felt viciously please watching traitors slowly die.
Robb would have never promised mercy and then left them to hang from trees.
The surviving Tullys tell her she looks like Catelyn, and when she takes back the north she hears the lords whisper she is like their dead king.
She doesn't think her mother would have ordered the Boltons torn apart by wolves, she knows Robb would have been horrified at the thought of it.
But her brother did not learn what winter meant, her mother never stopped him from being a fool.
They lost the north and she took it back.
She feels more a Stark than either of them.
