No, see my response above. That's actually unlikely. Ironically her pregnancy saved the character. They were planning on having her be the big bad of the season and killing her off at the very end.

Dochawk on the ATPO Board was best friend's with one of the PA's and managed to spoil me for the entire season. Apparently she was late to filming and caused multiple delays. Fox and WB requested Whedon put an end to it.
