A prince from an overthrown planet comes to Earth and, with his guardian, tries to fit in at an school while trying to avoid assassins who have come to Earth to kill him.
Matt and Walt plan to expose the assassin posing as a student by checking pulses in class. Anyone from Quadris would be twelve beats per minute. But the assassin (had this one been unrobotic) would have been one of the invaders and not Quadrian. It could have had any pulse, or none at all.
Edit
The speeding bus footage was a combination of the film shot in the pilot and only new video was needed of the interior of the bus. A few students were wearing the tacky jackets worn in the pilot to match up the scenes.
Edit
During the filming of a stunt for this episode, Peter Barton was badly burned by a magnesium flare. Production of the series had to be halted for several months while Peter recovered, and the debut of the series was delayed for a year.
Edit
Matthew: They'll keep coming, even if we run. No, Shep, no more. I have the powers and I want to fight.
Walt: What if you lose?
Matthew: I'd rather lose fighting than lose running.
