The way the Doctor sort of just shows up - sonics the pool of goo - and runs out - makes me wonder if that's not the Doctor crossing his own timeline again like last season. Maybe that's why the older Doctor has been running for so long. He's been trying to undo all the things his "oncoming storm" persona has done or maybe it's to do with that whole "doctor falling so far" thing. He's been trying to fix it.
I dunno. It just seems like it could be a really interesting way out.
I like it.
