Littlefinger tries to convince Sansa to turn against Arya, but what he doesn't realise is that despite the years of separation, the sisters' loyalty has remained whole. The women conspire to expose his crimes in a public shaming, revealing that Littlefinger poisoned their uncle Jon Arryn, King Robert's former Hand — an event that sparked the War of the Five Kings. He also turned their aunt Lysa Arryn against their mom, Catelyn, betrayed Ned Stark, and shoved Lysa through the Moon Door. Lord Baelish expresses remorse for his crimes and pleads for mercy, but Arya cuts his throat with the same Valyrian dagger integral to each of his schemes.
