That Scotty - using the old Rigelian Kassaba Fever trick and getting the Kelvan Tomar (Robert Fortier) wasted on cheap booze! This while Bones is drugging Hanar (Stewart Moss) with vitamin shots, and the Captain is seducing another space alien-babe (Barbara Bouchet as Kelinda). Getting the Kelvans to OD on human emotions seemed to have done the trick by the end of the episode, as their leader Rojan (Warren Stevens) finally agrees to Kirk's suggestion to have the Federation find them a place to stay. It's a bit of an anti-climactic resolution considering the Kelvans were starting out to conquer an entire galaxy, but hey, that's the way it goes sometimes.
It wasn't often that the writers mentioned a series continuity element, but they did it here by recalling Eminiar VII and Spock's prior use of a Vulcan Mind Probe. That would have occurred in #1.23 - A Taste of Armageddon, and I don't seem to remember it now, so I'll have to go back and take a look.
Another interesting point was made about the idea of intergalactic travel. With the Enterprise routinely engaging in multiple warp factors and the distance between galaxies being impossibly distant to comprehend, the idea that it would take the commandeered ship three hundred years and more than a few generations of Kelvan and Earth descendants to get there was a nice touch. By then, Kirk and Kelinda might have created an entirely new species.
