Secret (13th Doctor x River Song)

River Song has already spent her last moments with the Doctor on Darillium but it seems they have bumped into each other once again. The Doctor must keep her identity a secret in order to avoid a paradox but it proves to be quite difficult as they face a familiar threat.

Madame Kovarian and the Kovarian Chapter have forced their way back into the picture with unfinished business. They know that the Doctor somehow survived, eventually reaching Trenzalore still cheating death, and Madame Kovarian is not happy about it. With both of their lives at stake they must find a way out without River discovering the true identity of her new friend.
