Ok so I've never advertised that I have an ao3 account on which I post stuff because I'm very self conscious I guess, but I just finished this short fiction about Ruby. I, like a lot of people, was not happy with the reveal of who Ruby's mom was.
I could pull up so many small details that made me theorize that it was Kronos, the cronovore from the 3rd Doctor's story "The Time Monster". But since we didn't get that I thought I'd write this. If your interested, why not give it a read?
