But if you render all the organics unconscious, it's trivial to just search the ship for him deck by deck. But then again, these Changelings were short sighted enough to give themselves lungs and can die in space, so maybe that wouldn't have worked. lolApparently, she needs Jack alive, and wasn't sure where he was on the ship, since she had to send goons to find him. I guess cutting off their "sight" works both ways (Ron Moore was right, there's too much damn technology in Star Trek, you have to call out that you're inhibiting the transporters or jamming the internal sensors if you want anything to take any time or effort).
Because she was tortured and cut up by the S31 scientist whose face she wears now. Her identity is formed in that moment — she exists there.
It's just odd characterization. Her intelligence changes based on the needs of the plot and isn't consistent.Villains usually are silly. Vadic was in pain, clearly suffering and sadistic. It makes sense to her. Sufficient for me.
Mileage will vary.
I don't mind turning her into a generic mustache twirling villain, but it just seemed like a massive departure from the character who was happy to let the Titan go if they handed over Jack way back in episode 2 or 3.
