How she goes out: Jaime leads Cersei down to the tunnels below the Red Keep where the dragon skulls are in hopes of escaping through a secret passage that leads to the shore outside. Tyrion had promised a rowboat would be waiting there to transport them to safety, but by the time the doomed lovers arrive in the crypts, the passage has caved in and they soon realise they're trapped. The ceiling begins to crumble around them, leaving the Lannister twins dead and buried in the rubble of the castle they fought so hard to control.
