The Brightest Night
The first time the snake was mentioned was in the Scorpion den when it was found and caused a fire somewhere in the place. Although it wasn't mentioned, it was explained to Sunny what it was and what it was capable of.
It was then first sighted when Burn opened the box Blister gave to her that had two of the vipers in there which killed her and nearly killed Clay. It was from the box Sunny saw when she first came into Burn's stronghold
