In a leaked interview, which has since been taken down, Alex Kingston revealed a few major spoilers for seasons 7 and 8 of Doctor Who.
She first reveals that she will be on the s7 finale, which most of us expected. But even more excitingly, Alex teases a big secret that River has been hiding. She also notes that River will play a major role in s8.
With many mixed feelings expected to come from the Whovians, bloggers are urged to prepare for rants, multiple theories, and all-around fangirling.
