Scorpion - "Once Bitten, Twice Die"
In this thrilling Scorpion episode, a national leader was positioned with venom while Team Scorpion was called to a summit to help with a secret peace treaty.
In order to make an antidote, Walter needed to obtain another sample of the venom, so he broke into the local zoo's enclosure and coaxed the same species of snake to bite him.
