"You'll be fine, Jack." The Doctor spoke into a microphone after configuring the settings to make sure the Captain could hear him alright. "They are done evacuating, so it's just the two of us and a lot of stuff that could kill us. Just like old times. I take it back, maybe it's a date after all. I'm a great romantic." He hoped his fairly poor attempts at humour might cease Jack's worry. "Alright. Do you see the broken valve? There should be a replacement piece somewhere nearby. Looking exactly like that, just, well, not broken. Do you see it?"

He tapped his fingers against the wall, not aware of having fallen back to the familiar rhythm. One, two, three, four. Always there at the back of his mind. "Thank you for the view, by the way. I'll see if I can get security camera footage, maybe we can sell it."
