Recap
A meteor hit the earth, causing a sonic wave that shut down all the power in Terra Nova. Taylor attempted to get the power back on while trying to protect the colony from invaders. Mira distracted Taylor with a dinosaur and snuck in the back to steal a box from Terra Nova.
The box, which couldn't be opened by anyone in the colony, was given to Lucas - Taylor's son. He opened it to find equations and symbols. Lucas seemed to be ready to put that information to good use.
Meanwhile, Elisabeth used Skye's help to save a friend from a deadly parasite and Maddie had a romantic escapade with her friend.
