LoglineWhen the USS Enterprise investigates an attack on a colony at the edge of Federation space, Captain Pike and his crew face the return of a formidable enemy.
I would like to know why the Gorn was there too, but the Gorn didn't notice Spock boarding and so there's no reason to believe Enterprise would have notice a Gorn boarding. It's also possible it was beamed over when the Cayuga was destroyed to find something or to access the ships systems.
