"Never tell me the odds!" seems to be the apt sci-fi quote to apply in this situation as described by The Gentleman's Armchair.
If I remember correctly, that quote was spoken in one of the last seasons of Star Trek by Han Solo, while piloting Serenity and running away from the Cylons. Yes, I'm sure that's it!
No. It was the Vorlons, not the Cylons. You're thinking of Exosquad.
