I can honestly swear that I never intended my actions to be interpreted any way other than a good Starfleet yeoman following the call of duty by seeing to her captain's every REASONABLE need.
He said that his back hurt. I reached out, and tried to fix it. I didn't even notice Mr. Spock at first, not until I realized he was glaring at the captain--and at me.
Spock doesn't have to be jealous of me. I know the captain only has eyes for him. I'm just a yeoman, doing my job.
Besides, I happen to like blue eyes.
