All we know for certain is that the girl is of timelord origin.
It is also clear that the Silence needed her for some reason.
They also needed a space suit.
We still dont know the significance of the ship. Is it the Ackerman road ship? or just of the same type? Scavanged?
Amy was told by the Silence, 'we honour you' & 'she will bring the silence'.
The silence must have time travel capabilities, They had what was strongly suggested to be Amy's daughter. The child had not been born yet but was exisisting in 60's America. The ship is very tardis like.
I wonder if a Timelord child regenerates, does it regenerate into the body of a child, or can the age be variable, like the doctor?
The next time we see her she will be very different. Could be any age, at any point in future history post 1969.
It will be interesting to see how Moffat proceeds with this.
