TEXT: Martha and the Doctor are at the console, the Doctor handling the controls as they're in transit. THE DOCTOR: There we go... perfect landing, which isn't easy in such a tight spot. MARTHA: You should be used to tight spots by now. Where are we? THE DOCTOR: The end of the line. Martha rushes towards the doors. THE DOCTOR: No place like it. Martha looks at him, questioning if she should open the doors. He nods and she goes outside only to be disappointed in the destination. MARTHA: Home. You took me home? THE DOCTOR: In fact, the morning after we left, so you've only been gone about 12 hours. No time at all, really. The Doctor begins looking about at her photos. MARTHA: But all the stuff we've done: Shakespeare, New New York, old New York? THE DOCTOR: Yep, all in one night, relatively speaking. Everything should be just as it was... Books, Cds, (picks up underwear drying on a rack) laundry. Martha snags the offending lingerie from his fingertips. THE DOCTOR: So, back were you were, as promised. MARTHA: This is it? THE DOCTOR (inhales deeply): Yeah, I should probably... um... Martha's phone rings and the answering machine picks up. ANSWERING MACHINE: Hi! I'm out! Leave a message! MARTHA: I'm sorry. The machine beeps before Francine's message. FRANCINE: Martha, are you there? Pick it up, will you? MARTHA: It's Mum. It'll wait. FRANCINE: All right then, pretend that you're out if you like. I was only calling to say that your sister's on TV. On the news of all things. Just thought you might be interested. Martha picks up the remote control and turns on the TV. We hear the voice of Prof. Lazarus before we see him. LAZARUS: The details are top secret... MARTHA: How could Tish end up on the news? On the TV screen we see Prof Lazarus, who looks
SUMMARY:
76-year-old Professor Richard Lazarus demonstrates his experiment where he uses hypersonic sound waves to restore his youth and cheat death. The experiment mutates his DNA, unlocking dormant genes in his body and turning him into an evolutionary throwback that drains life energy from his victims. The Doctor reflects the energy of Lazarus' sonic micro-field manipulator onto Lazarus, causing him to flee to Southwark Cathedral . The Doctor uses the acoustics of the cathedral to create sound waves from the church organ, which causes Lazarus to fall from the bell tower, finally killing him. The Doctor invites Martha to travel with him full-time rather than her just being a passenger.
