Romulan Commander And Spock

In The Enterprise Incident, Spock must team up with his Captain for a sort of James Bond meets Jason Bourne mission.  Stealing a Romulan cloaking device isn't easy - the job tasking Kirk - but romancing a steely Romulan Commander may be even harder.

Only known as the Romulan Commander, actress Joanne Linville brings a classy and smokey sexuality to the character and always makes us wonder if Spock will be able to resist her temptation.
