Proof for Daenerys

Description

As part of their plan to capture a wight as proof of existence of the army of the dead, Jon Snow and his men ambush a group of Wights led by a White Walker, lighting a campfire to get their attention. Jon himself kills the White Walker, at the same time destroying all but one of the wights under his command. While taking refuge from the wights on an island in the middle of a frozen lake, Beric Dondarrion advises Jon to kill the recently arrived Night King, potentially ending the threat of the Walkers and their army.
