The eyeball ship appears to scan the area, and the Doctor blows up a phone booth, but this somehow destroys his screwdriver, and the eyeball loses interest. The Doctor whines about this, and the man-and-dog vanish and slip down a helpful drain grate. So now we've got no TARDIS, no screwdriver, and seventeen minutes. And they don't even know how crummy it is, because also Zero is now at the hospital being all kinds of menacing.
Amy and the Doctor make a nonverbal agreement to actually use complete sentences, since they have seventeen minutes to chat and fuck about, and he confirms for her that yes, the dog-and-man has been hiding in her house for twelve years, which is a blip to a Multiform like Zero, and that it was the Doctor who led the eyeball ships to Earth today, rather than them showing up when it first escaped, the answer to a question nobody cares about, because of that time the eyeball saw him through the crack. "They're only late because I am," he says, and then goes back to be annoyingly uncommunicative, snatching Rory's phone and doing stuff to it while they talk about the Doctor and how Amy used to make Rory dress up like him (when they were kids, don't be gross) and how these are all coma patients, which we knew. Eight comas, eight disguises for Prisoner Zero -- including a dog this time, because there's a dog in the guy's coma dream. Clearly, what this means is that the Doctor needs a laptop.
Which is fine? Except the only reason he's acting like this is for the emotionally manipulative, dorky moment when we get the punchline to why he demanded the phone, or why he needs a laptop, or who he is, or why we only have twenty minutes, and the whole episode is like that: People acting woefully annoying in order to set up jokes and cynical "WOW!" moments later, and it's obnoxious, because if you could tell a story properly you wouldn't be constantly having to hit us over the head with how amazing and magical every fucking thing is: They would just be amazing. All on their own.
"Your friend, what was his name? Not him, the good-looking one." Rory's offended, and even more offended when he realizes they're talking about Jeff, and the Doctor only remembers him and his hotness because he needs a laptop for whatever reason, so he sends still-confused Rory and up-for-anything Amy off to evacuate the hospital so he can go hit on Jeff some more.
