It’s getting so close you guys. SO CLOSE.

3. Who is River Song?

Professor Doctor River Song

Here are some answers that would disappoint me:
1- River Song is Amy Pond.
2- River Song is the Master.
3- River Song is the Doctor’s wife/daughter/mother/whatever.
4- River Song is Jack Harkness, or Jack’s wife/daughter/mother/whatever.
5- River Song is Jenny.

This is one of those things where I’d rather not know the answer. Some things are just better left to the imagination. I would like to know, however, who she has killed. But In Moff We Trust, so hopefully he gives us something extra awesome.
