Spender, Kalinda, Addison, Tann, Morda. In that order.
Frankly, I'm disappointed Bioware didn't give an "impulsive" option for Spender's fate to drag him by his hair to the nearest airlock.
Kalinda? I wanted to try and like her, until she showed up on the ship, at which point I knew I'd be gunning for her head. "Ta?" "DIAF." And then I get my wish. :D
Addison, I wanted to strangle in the first conversation.
Tann is a racist *, but to be fair he was also quite hilarious. Especially the moment at the end of Pathfinder Hall's introduction, where he uses some cheesy upbeat line and then groans at the end of it.
Morda kinda ticked me off with her antagonism, but with her I at least understood why she was so antagonistic.
