Doctor Who - Professor River Song

Watched the latest episode of series 10 of NCIS on channel 5 last night, and Alex Kingston appeared in the show in the episode 'Gone', so I joked to myself that when River is not with the Doctor, she likes to spend her time on 21st Century earth in America with NCIS Special Agent Gibbs.

And there I was thinking River was either spending her time in prison at the Storm Cage Containment Facility or being more or less dead on the Library planet.
