If she'd wanted to, she could have played it up even more. I love how she used her sexy in "Counterpoint." However, I'm impressed with KM's restraint in that regard, because too much sexy and she would have reduced Janeway to a sex object, which she certainly did not need to be in order to be a BAMF!
Yeah, she walked that line very well.
What the hell is a 'BAMF'?
