Eleventh Doctor
The Doctor uses both of River's catchphrases – "Hello, Sweetie" and "Spoilers". River's last line to the Doctor is "I hate you", to which the Doctor replies "No, you don't". This is banter River and the Eleventh Doctor often used, such as in "The Impossible Astronaut". River is also shown as possessing a red fez, a favourite headpiece of the Eleventh Doctor.
