When the door opened, Troy was rubbing his hands together and smiled as his cousin made his way towards the machine and observed it. Troy's head bobbed in an eager nodding fashion, then laughed as John figured it out, his hands holding open immediately, "Yes! Yes, yes... it's a thing. And yes, I think it does that thing that you think it does, I'm sure of it, though I'm not entirely sure what this is for..."
He pointed towards Clara's hairclip, "Seemed prevalent at the time, but now I'm not sure why... hasn't really done much, if it can do anything. Not sure, but yes I think it does that. I wasn't really sure when I started building it, but then it kind of just came to me, and then I knew. It could find the TARDIS. Well know that it should find the TARDIS, not that it could, hasn't yet, bit of a presumption on my part."
Troy spun on his heel and moved back towards his computer showing it, "My problem is, I'm not sure where our dreams are from. Are they from a different world, universe, dimension? Are we actually the Doctors true to form, or did we actually live our lives and our Doctory selves lived theirs separately, and we're meshing? It's odd, really. Still, I have it sweeping where it can, but it can only do so much. I'm missing a thing, I should think. An important thing, and not really sure what that might be..."
Finally Troy stopped and looked back at John, "And right, how have you been?"
