I've stayed away from Merlin, because my geeky medievalist is going to flail worse than when SG-1 did king Arthur.

I think the best attitude for Merlin is to pretend it's set in some alternate medieval universe, rather than this one. I don't know a lot about medieval life, but even I know they don't go around saying 'ok'.

Last week's Criminal Minds was freaking tragic

It really was. I hate the ones where I end up feeling like it would have been better for someone if they had been killed :( The depressing thing is, it wasn't the plot that made me cry, it was the bit at the end with the team and JJ and the baby. There's no hope for me!

I know they are all your work, but I can't help but feel like it's my universe just a little, and it's a warm fuzzy feeling every time it grows.

It's definitely your universe a bit, you put the idea out there in the first place. I like that it's shared anyway, especially with dossier writing a bit for them as well.

Can you recommend a good beta?

For something with Numb3rs, sadly no. The people who've ever beta'd for me don't watch it. I'd offer, but I'm kind of crazy busy at the moment, and I just don't have time. You could try fandom_betas, someone there might be able to help.
