Primary Objective: Determine if Romulans are using Klingon technology and have a new cloaking device. Secondary Objective: Capture said device. Use it to facilitate escape if possible. The secondary objective is very unlikely, so why the hell are they risking such a valuable asset as The Enterprise for an information mission? First you have to assume the Romulans don't just start blasting away as seen in The Deadly Years. Then, having only Kirk and Spock in the know is extremely dangerous. Scotty could have fouled the whole thing up by staging a rescue mission had the Romulans just held onto Spock and Kirk or kept them separate. As McCoy said, it's a good thing an autopsy wasn't ordered. Also staging Kirk's death so they could give him surgery and put him back on the Romulan ship? Kind of contrived.* A million things could have gone wrong. I did like how everyone in the crew (except Sulu) had some little things to do. And Joanne Linville was great. I loved her look when she slaps Spock and when she steps onto the Enterprise bridge to see that Kirk is alive. *If I could rewrite the episode, I'd have Spock on leave and Sulu second in command. Therefore Sulu could play the 'Spock role' in this episode (Have to leave out the Romulan-Vulcan connection bit) it would give Takei a lot to do in the episode and would be a cool moment of surprise to have Spock show up 40 minutes into the episode in a Romulan uniform ready to beam over and get the Cloaking Device. Gives Spock some 'action Spock' moments nerve pinching and karate chopping the Romulans Kirk took out in the original ep.
