You're a very stubborn man, Mr. Spock [Galileo 7]

I totally love that scene on the Bridge at the very end of Galileo Seven. When Spock said that it was logical react emotionally, to try a desperate action, when there was no alternative.
Jim points out that he's quite stubborn and Spock answers "Yes, I am".

Love Spock and Jim's closeness here humm~ Kirk is totally invading his Vulcan's personal space XD
