Montage: The Doctor and Margaret enter her restaurant chatting and holding hands, because of the bracelets: the snake you put in your pocket so it won't go loose. Captain Jack lies alone in the TARDIS, still messing about with wiring: the snake you put in your pocket because it's pretty, which...may or may not be a snake, depending on...the memories that were stolen from it...by Time Agents. Yeah, the metaphor kind of breaks down. Mickey walks Rose down the sidewalk, happy and in love: the snake you put in your pocket because you can't help yourself. As the Doctor and Margaret take their seats, Jack gets the lights on the extrapolator to flash, and smiles wonderfully. I don't know what the parallel structure here is supposed to...oh wait, yes I do. It's not the TARDIS that Jack's on a date with, it's the extrapolator: the snake you put in your pocket because it was shiny and made you feel strong. That's smart. And necessary! Good job.
As the Doctor and Margaret peruse their menus, she chastises him: "Here we are, out on a date, and you haven't even asked my proper name!" He squeals that it's not a date, and immediately asks her name. She tells him it's Blon Fel Fotch Passameer-Day Slitheen: "That's what it'll say on my death certificate." He says that it's nice to meet her and goes back to his menu. She stares over his shoulder. "Look...that's where I was living as Margaret." He turns around, and Blon empties a little powder from a poisoner's ring into his glass, chatting about its real estate stats. He turns back around and swaps their glasses with a smile, and goes back to his menu. She smiles sarcastically, he smiles a bit less. "Tell me then, Doctor," she says, "what do you know of our species?"The Doctor says only what he's seen, which I guess means killing and farting. Blon adds, "Did you know, for example, in extreme cases -- when her life is in danger -- a female Raxacoricofallapatorian can manufacture a poison dart within her own finger..." And then she shoots a dart at him from her fingertip; he catches it without even looking up. Dude, he's so awesome. "Yes I did," he says pleasantly, and they sort of joke around how awesome this date is turning out to be. Blon leans in close: "And one more thing, between you and me..." He leans in tight, as well, like there's a secret to be had. "As a final resort, the excess poison can be exhaled through the lungs. HOOO!" Blon breathes out a green gas, and the Doctor squirts her mouth with breath freshener. "That's better," he says, and leans back. "Now then, what d'you think? Mmm, steak looks nice. Steak and chips!" She's kind of disgusted as she goes back to her menu. That reminds me, I haven't watched Mr. & Mrs. Smith in, like, hours. Be right back.
