As they do every week ;)
1. When we meet Doctor Song, she's on the run - but she has an escape plan involving The Doctor.
2. The episode includes the caption "10,000 years later."
3. There's a Weeping Angel trapped inside the Byzantium.
4. First mention of "spoilers"? 9 minutes 27 seconds.
5. Amy: "Is River Song **** ****? ... "She's *** ****** from the ******, isn't she?"
6. There's a device that harks back to 'Silence In The Library'. Think "hey, who turned out the lights?"
7. Amy should really learn that too much TV is bad for her eyes.
8. The Doctor. Bites. Amy.
9. River: "I have pictures of *** **** *****."
10. The cliffhanger isn't the usual sort of two-parter cliffhanger we've grown accustomed to with new Who. Despite being very familiar.
Can't wait to see how number 8 turns out.
