Doctor Who: 20 Things You Didn't Know About The Ninth Doctor
17. He Also Met River Song!
Like with Sally Sparrow, we never saw the Ninth Doctor meet River Song on-screen, but he did bump into his wife in the expanded Whoniverse.
The Big Finish audio series Star-Crossed teams up Alex Kingston and Christopher Eccleston and takes the two characters from a high-security intergalactic bank, to a run-in with a sinister dating app.
Another encounter of theirs was depicted in the video game Doctor Who: The Eternity Clock. Throughout the game, players can collect many different pages of River's diary, each containing some fun lines of dialogue written from her point of view.
On one of these pages she talks about the Ninth Doctor, noting his "leather jacket", "funny accent", and "big ears", while also mentioning that she shouldn't talk about "the war" around him, which is a nod to the Last Great Time War.
And yes River, it's really not a good idea to mention that around him. He gets angry!
