I have no strong feelings either way towards Omega, that's just the rumor I've heard. It's obviously someone time lord related, seeing as how they could operate the tardis from outside the ship. I just hope it's not the Master, that'd be way too soon. If I had my way it'd be Valeyard.

I also dig the way they're handling River. She does seem to be subtley younger each time we see her. The concept of them going in reverse is fascinating but at the same so obvious I can't believe no other Doctor Who writer has thought of it before. At some point I would like to see her as a permanent companion for a year or so and then have her guest starring as someone getting to know the Doctor while he already knows her intimately.

Bow ties are coool.
