John and Derek infiltrate a military academy to protect a future member of the resistance. Meanwhile Sarah and Cameron have to protect a moppet from an Arnie like Terminator. John and Derek bond over huge guns and getting the other cadets to help kill a Terminator by disguising it as a training exercise. John's still alienated from Sarah, she only has herself to blame.
Meanwhile Catherine and Ellison bond over hunting other Terminators. Ellison doesn't notice Catherine's creepy body language or how she kills a man in a truly revolting way. This was okay with nice drama and the Terminator killing exercise takes place to a bizarre 'Wizard of Oz' voice over.
"Blow its head off."
"He can put it back on."
