ok, so, we have another "arc" that will hopefully be figured out by the end of next series. "silence will fall". there is the mysterious voice, the control of the tardis that made it explode, perhaps even the organizing of the "alliance" and the maker of the pandorica, but is there more?
going back through this series, there are a couple of unanswered questions, and perhaps, with anyone's help, you can point out more.
first off, the smilers. half-human, half-robot(?), what really were the smilers, and what was their real motive?
B: when amy was in the "forget" booth in the beast below, she got a message from herself begging her not to let the doctor continue to investigate. is this really a clue from the "silence will fall" arc? perhaps the doctor's involvement in the beast below will lead to the "silence will fall"?
3: the voice. it's either a really angry old person(hawthorne?), or it could be the voice of the smilers. they sounded robotic, and the voice kept repeating "silence will fall"
my thoughts are that perhaps the adventure with the beast below will somehow tie into the arc. we already saw the return of liz10 in the pandorica opens, and i don't think it will be the last time we will see her. if she gets killed helping the doctor, could the "silence will fall" be some kind of revenge from the smilers?
just some random thoughts.
