Aha! I thought something was up with that hand. Every time they showed an interior shot of the Tardis, the camera would linger for a second or two on that hand. Finally got used to make another Doctor.
Something curious I noticed, may be nothing but it may be something: after the Doctor wiped Donna's memory, he leaves and we see Donna chatting on the phone. She's wearing some sort of ring, a ring I never noticed before. And the light reflects off it. I'm assuming we wouldn't see that glint or flash of light for no reason. Hmm...
And speaking of rings, when The Master was burnt up in that funeral pyre, someone came and collected a ring from the ashes. Did he transfer his essence into that ring or something?
Oh and the fake Doctor who makes a hot air balloon Tardis...that's The Governor from The Walking Dead, innit?

People think "queue" is just "q" followed by 4 silent letters.
But those letters are not silent.
They're just waiting their turn.
