Question: Is there going to be a final episode of Enterprise? If so, when will it air? — Tanya

Ausiello: The final two episodes will air back-to-back on May 13. The first one, "Terra Prime," will wrap up a two-episode arc featuring Robocop's Peter Weller as a well-armed, radical human isolationist leader who threatens to destroy Starfleet Command unless all aliens leave Earth immediately. And the second one, "These Are the Voyages...," will take place six years in the future as an emotional Captain Archer and Co. return to Earth to face the decommission of Enterprise and the signing of the Federation charter, ratifying the newly formed alliance of planets they helped forge. And then, in the final scene, Spock shows up and does the Macarena.
