After Moffat took over from Davies as executive producer, River Song was in the 2010 series. At an earlier point in her timeline, in the two-episode story "The Time of Angels"/"Flesh and Stone", River meets the Eleventh Doctor (Matt Smith). She is more familiar to him and he is more familiar to her. At this point in her life, River is a doctor. She is not yet a professor. She leaves coordinates for the Doctor to find so that he may save her in the 51st century. With him she goes to learn about the crash of the spaceship "Byzantium". She shows herself to be better at flying the TARDIS than he is. She tells the Doctor that she is imprisoned in the Stormcage Containment Facility for killing, in her words, "the best man I've ever known." An even earlier version of River helps the Doctor in series finale "The Pandorica Opens"/"The Big Bang". After Winston Churchill (Ian McNeice) talks to her while she is in prison, she takes the Doctor to 102 A.D. While River is travelling in the TARDIS on her own, it explodes with her inside. The Doctor, using an device that belonged River, is able to save her and teleport her out. She then helps him in closing the cracks in the universe. After the Doctor removes himself from all of history to close the cracks in the universe, River helps Amy Pond to remember the Doctor. This brings him back. She gives Amy her now-blank diary. At the end of the series finale, The Doctor asks her whether she is married. She says she is married, and answers yes to a question she pretends think is him asking her to marry him. She then tells to the Doctor that he will soon learn the truth about her, after which 'everything changes'.
