The team having got rid of a crooked FBI agent go to Paris to pursue the bears but these bears have mutated, developed an exoskeleton. The Mother Cell could be responsible for this and it might the proof they need about Reiden.
Mitch though is pursuing his own agenda, it looks like the team is not as united as we thought.
It seems Zoo is just a bonkers series that is all over the place which this week includes an hi tech heist.
The episode title comes from the name you give to a group of bears.
