Which begs the question, what *would* he have done in Horizon had Cally agreed to go? Dithering around until An Excuse to Do The Right Thing is a little harder to manage when someone's actually there watching you ... would he have bitten the bullet and left Horizon (and never forgiven Cally for 'making' him live up to his own bad image) or suddenly found a pressing if self-interested reason why they had to make *absolutely* sure ("Vila stole my second-best laser probe and took it with him, I don't care about them but I'm not leaving without *it*.")
Oh, I would love to have seen that! And then a smirk on Cally's face that tells you she *knew* he'd come up with an excuse.
