After encountering the electrical fence when playing as Nima in Episode 1: The Intruder, there is a sign that can be interacted with that reads "Danger 1000 volts". If you select the sign, Nima will question its significance. Select it a few more times and Nima will say "1.21 gigawatts? Why so much?". This is a reference to the amount of electricity necessary to power the Flux Capacitor in Back to the Future. It is worthy to note that Telltale games released a Back to the Future video game prior to Jurassic Park.
