DEEP SPACE: "Past Tense, Pt. II" - 10/31/94 - ACT ONE 11. 7 CONTINUED: KIRA (V.O.) First Officer's Log, supplemental. Somehow Sisko, Dax, and Bashir have altered Earth's history. We have no choice but to send an away team into the past, to try to find them, and to correct the changes to the timeline. The only problem is, we're not exactly sure where to look... or when. 8 INT. DEFIANT - TRANSPORTER ROOM (OPTICAL) ODO watches as O'BRIEN, in his civilian clothes from "THE HOMECOMING," prepares to beam down. O'Brien's being assisted by the N.D. CREWMAN who was helping him in Part One. O'BRIEN According to our computer simulations, the degree of temporal displacement is directly proportional to the number of chroniton particles interacting with the transporter beam. Unfortunately, there's no way to know the exact concentration of particles at the time of the accident, but I've narrowed it down to ten possibilities, each one corresponding to a different time frame. One of them has to be right. (a beat) We'll just have to hope we find the right one before we run out of chroniton particles. KIRA ENTERS, also dressed in civilian clothing. She's got a small gray bandage across the bridge of her nose, hiding her ridges. She's not wearing her earring. KIRA I feel ridiculous. ODO Well, it does effectively disguise your Bajoran heritage. O'BRIEN If anyone asks, just say you broke your nose.
