JACK: Arkan leisure crawler, first generation. Collectors' item. Don't see many of those around these days. Tosh, send a polite message saying great to see them, but could they please get the hell out of our atmosphere, they're spooking the locals.

TOSH: Done.

GWEN: Shouldn't we be apprehending it? Investigating it?

JACK: Oh, please. You interrogate an Arkan, you'll be in there for a month. And that's just the first question. They are so boring. Besides, they're mostly made of liquid. The cells would be a mess.

IANTO: Lisa, please. I brought you here to heal you, so we could be together.

LISA: Together. Yes. Transplant my brain into your body. The two of us together, fused. We'll be one complete person. Isn't that what love is?

IANTO: No.

LISA: Then we are not compatible.

IANTO: You're not Lisa.

ANNIE: You always said you didn't love me for what I looked like. Last time you said that, it was a Saturday. We were hungover. You made cheese toasties, and moaned I hadn't descaled my kettle. That night, we camped on a beach in Brittany. It got so freezing we wore our coats and shared one sleeping bag. When we woke up the next morning, a dog was pissing on our tent. Hold me, Ianto. I need you to hold me. I need you to tell me it's all right.
