[that bubble thing is...odd. Oliver is not aware that he has one over his head showing a blue police box] Well, I think making a time loop is just a matter of having the right technology. Or...I dunno. You'd be surprised how time can work. The Doctor could probably explain it properly. [now there's a little Doctor outside the blue police box]

But I think we're stuck in more than just a time loop. I mean...whatever's going on on this ship seems more complicated than that.
