Ok, this is a little complicated. The actor who portrayed the Tenth Doctor, David Tennant, is engaged to marry the daughter of the Fifth Doctor, Peter Davidson (story here). The couple met when she guest starred on Doctor Who and portrayed a character generated from The Doctor’s dna. So we have not one but two layers of some sort of weird pseudo-incest going on here, and we’ll be lucky if this doesn’t create a rift in the space-time continuum of some kind.

Now I knew that Tennant was a big fan of the Fifth Doctor, but this seems to be taking things a bit far. It didn’t work out too well for Elvis fanboy Nicolas Cage, after all.

I have already informed major league Tennant fangirl, The Misses, of the news.

This was her reaction.

Update
Ok, technically this was her reaction. But I think I captured the general sentiment.
