Hi Vaughn and Tracy
I was wondering what that gizmo Spock carries around for all of "That which Survives" was too. For a while I thought it was the remote for the viewscreen...but then I recognized it! It's the "Spock Controller" McCoy used in lieu of a space-stretcher in that episode where those women stole Spock's brain.
Maybe the prop guy just figured Spock needed something to hold so it looked like he was doing something; but I prefer to imagine McCoy did a predictably shoddy job stuffing Spock back in his body and some of his brain-wires came unglued.
"That Which Survives" is a lot more fun to watch if you're imagining Spock's acting weird because every time he gets out of a chair, he has to remember to hit the "clench" button on his remote so he doesn't dump a load in his pants.
Another great Podcast...Thanks.
