Is Morena Baccarin Inara? I'm so bad with names :p

Yup, she is Inara. I could imagine her as a Reaper. It would sure be nicer for Dean than the last one he encountered. :)

Man, someone promised to upload the Still Life pilot and and I still haven't found it *whines*

I haven`t seen the whole thing, just a few clips since I only have a dial-up connection anyway.
One clip had Morena and Jensen in it and they seemed to have chemistry.
