Doctor Who Who is the little girl in the Impossible Astronaut?
i have many theories for that.
1. It is the Doctor and River Song's child. This seems possible because they always meeting at different times so the Doctor didnt know her when he saw her. However River Song would know her but in the show River Song hasnt seen the child yet. Also the reason for the photograph is that Amy could have raised her for awhile because River Song is in jail and the Doctor didnt know about her.
2.It is a reincarnation of Jenny. (This one is very far-fetched and i dont think Moffet will ever bring Jenny back)
3.They always mention the Doctor having children so maybe she is one of his children who escaped like the Master did. They dont recognize each other though because they both have had multiple regenerations.
4.The Doctor knocked Amy up. (This one is just a funny idea)
What are your ideas or thoughts?
