Well now I know who "Whistleblower" is. He's a dillusional poster on GB that goes by the name of R.E.D, who's been trying to push his frankly ridiculous theories about what's "really" happening in the series (including The Doctor being dead since The Big Bang) on people at every possible opportunity.
Yeah the second I saw Omega mentioned in there I knew it was a fake. Fans have been talking about his supposed return for years (along with the Rani and Valeyard), even though it is something that Moffat clearly has no interest in.
A shame. I think Omega would be ideal for A Matt Smith regeneration story.
I'm also desperate to see the valeyard again, although I think he'd work better as a 12th doctor enemy. Although I hate the Rani in what I've seen her in, I think she could adapt well on screen if done properly and modernised.
