Arya Recovers Her Sword, Needle

Arya’s sword, Needle, is stolen by a Lannister soldier in SE2 EP3, “What Is Dead May Never Die”. When Polliver & Arya cross paths again in SE4 EP2, “Two Swords“, the murderer doesn’t recognize Arya until it’s too late; just before she runs him through with Needle. Revenge is indeed a dish best served cold.
