 Yes, yes, hello, come on in, come on in, get in with the cameras, can see you, very nice, fill up all the space, there's plenty of space, just make sure you can see me, I'm not one for the spotlight usually, but very important, welcome, I am Dr. Sullivan, you can call me Harry, if you'd like, that's my name, lovely, welcome to the unit black site, consider yourselves lucky, we don't just let any Tom Dick or Harry Sullivan in, it's just a little joke, I assume you all know why you're here. A lot of blank stares, that's not very confidence inspiring, but that's fine, that's fine now, you are here because the doctor, yes, the doctor asked for you all in particular, we don't know why it was you, none of you are astrophysicists as far as we're aware, no, any knowledge of thermodynamics, any experts, blank faces, not the best, but that's fine, I'm sure your usefulness will become quite clear, soon enough, let's start with the basics, shall we? Does anyone know what artron or cronon energy is? Artron or cronon? A couple, yes, lovely, okay, well for the rest of you that's not so sure, that's fine, that's absolutely fine, artron energy comes from spatial travel, and you would get cronon energy from time travel, for example, you would get both of these types of energy in the TARDIS, the doctor's mode of transport, ah, yes, I looked at you and I knew you would know about the TARDIS, lovely, lovely, got one on your shirt for a start, it feels like that's a security risk, but that's fine, I'm just kidding, I'm mostly just going to draw, now of course, a TARDIS is not the only place you would get these two types of very specific, but fairly common energy, you'll also get them from the thing that's behind that door, the time fracture. In 1942, a bomb fell on London, this exact location, any history buffs in the room? Yes, you, I thought you were, that was during World War II, the height of the London Blitz, but this wasn't an ordinary bomb, oh no, this was a time bomb, more specifically, the time disruptor. Make sure you get a good look at this, because this is vital, this is what has caused this mess and hopefully, what will become our solution. Now, unfortunately, one of our own, Sergeant Robert Dudley, ventured into this fracture and, well, he's going to come back out again. So, since then, Dr. Leeson, our very own, was tasked with creating the PSGs to contain the fracture, and with these fantastic bits of apparatus, we're going to be sending some volunteers through to try and save Dudley, as well as save the whole running universe. Any volunteers, any volunteers, anyone at all? Ah, you, ah, oh, you as well? Oh, good, two, two off the boat, lovely. Jot some names down. There is no rush at the moment, we have two weeks, exactly two weeks of relative time to get this sorted, as well as doing some fun tests on the way. Dr. Sullivan, are these the volunteers sent by the doctor? They are indeed. Look at them all. Fantastic, they all look ready to go. Except for this gentleman here who appears to be yawning. Come on, wake up! We've got a universe to save. My name is Dr. Errol Courtney, and I'm in charge around here, so you'll all be listening to me. Now, Dr. Sullivan, I assume you've made them aware of the two-week window we have to, well, get this done. Of course, I've done the whole spiel. Well, we've just got a message from the big boss, Kate Stewart. It's now two days. So, if you want to hurry along, I'll be with you in a moment. Two, two, two days, he said, two. That's fine. I know I said two weeks of plenty of time, two days, seems minuscule. Why did you all follow me? Why did I show you in quite sharpish? Come on, let's go, here we go.
