The Wiki Files Episode V: Survival of the Fittest

Summary
In this episode, Ire wakes up and crawls out of the river, making a knife from a stick and hunting around for food. When night falls, he finds a cave and tries to start a fire, but doesn't have enough sticks. Leaving to get more sticks, he encounters a bear but stabs it in the eye with his stick, making it run away.

The episode flashes to the city where Arya works on tracking down the supposed killer, and she hires detective A5 to find the person. A5 suspects Batty, wrongly, and the two interrogate her for two hours before releasing her and finding out that she was innocent. They still don't find the "killer" and the episode ends with the hunt continuing.
