I'd hoped for more development, but like some poster said, maybe we'll see development when she returns.

Yeah -- I'm really hoping for that, too. I did really enjoy her last scene with the Doctor and I hope she carries that strength of character over into Torchwood and when she comes back on Who.

To me, DW's main underlying theme is change and this has been the most difficult one yet. They were askin' for it though when they decided to introduce romantic subtext '^^.

Oh, yes. There are few things that cause more conflict... at least in fandoms.
