Don't expect the season finale of Fox's Terra Nova to end with a bang — it starts with one! Airing December 19, the two-hour episode kicks off with the colonists warily awaiting the arrival of the 11th Pilgrimage. They're not sure if this is good news or bad. Bet on the latter. "Our evil guys, the Phoenix Group, will send somebody through the portal with a bomb, and it explodes," says exec producer René Echevarria. "Jim Shannon [Jason O'Mara] is hit by the blast and wakes up three days later to a very surreal scene — Phoenix soldiers have taken command of the colony."
