I just watched the last two episodes. Good shows, though the last was a little 'meh'. "Vincent" had the message that it's not the destination, it's how good the journey was. Dunno if that's important to the grander plot, but there you go.
Meanwhile, "Lodger" showed us that someone is trying to make a TARDIS? OR there's another TARDIS-type thing floating around there? Could be a source for the exploding TARDIS, anyway. But I guess the more important thing is that Amy found the ring, which caused the crack to widen, which proves... something.
Next week: the first part of the two-part finale. IT'S TOO SOON!
