“Mr. Chekov, you have the conn.” Spock handed the ensign the log pad and headed for the turbo lift. “I shall be in the main transporter room.”
“Aye-aye, sir.” Chekov sat in the captain’s chair and, as soon as the lift doors closed, spun it around to survey his new command, which consisted of Uhura.
“What’s wrong with the commodore?” Uhura asked with a frown.
“Simple,” Chekov replied with an all-knowing shrug. “I have seen the condition many times in the past.”
“And what condition is that, Dr. Chekov?”
“She is a starbase commander.” Chekov said it as if it was the complete answer to Uhura’s question.
“Meaning?”
“Meaning she is not a starship commander.” Chekov smiled widely. “Such as I am.”
“For the next half hour only, mister.”
“Some may think of it as a half hour,” Chekov said mock imperiously, “but I, on the other hand, prefer to think of it as…a start.”
