"Meanwhile," as though that concept applies, the TARDIS is going nuts: shaking, alarms, struggling, yelling. "Hold that one down!" the Doctor shouts, and "I'm holding this one down!" Rose shouts, and "Well, hold them both down!" shouts the Doctor, and so on. "I promised you a time machine and that's what you're getting," the Doctor tells Rose. "Now, you've seen the future -- let's have a look at the past. 1860. How does 1860 sound?" What happened in 1860? He has no idea: "Let's find out! Hold on!" They go all TARDIS-y through the time vortex.
Back in 1860, Mr. Sneed is sweating bullets due to his shittiness at his job, and the creepy screaming dead people, and still yelling for Gwyneth. I hope she has kung fu skills or something. That grandma was not screwing around. Gwyneth shows up looking not so hardcore, with some complicated hair and a fine set of choppers. Sneed tells her to get the horse and carriage ready, because Old Mother Redpath is laying a patch. Gwyneth has a similarly blasé, inconvenienced reaction, albeit with a hint of scandal: "Mr. Sneed, for shame! How many more times? It's ungodly!" Sneed and his muttonchops are like, "Not my fault!" He points out that grandma was eighty-six, so she can't be moving all that fast -- except, she was also dead, so I think the rules are a little bendy today. "What about Mr. Redpath?" Gwyneth asks. "Did you deal with him?" Sneed, again with the gallows humor: "No. She did." Daaamn. How'd Sneed get so hard? Gwyneth tells him he's awful, but begs his forgiveness for mentioning that "this is getting beyond, now." Sneed nods, so I don't know why all the bowing and scraping, but Gwyneth is all about going to get help. Sneed thinks that can wait until they've recaptured the screaming, glowing, ass-kicking old dead lady. He tells Gwyneth to "stop prevaricating," a word I do not think means what he thinks it means -- wait, no, there's an archaic meaning: "to fuck around" -- and then says, awesomely, "Girl, get the hearse ready. We're going body-snatching."
