It looked like Spock had everything planned out, and just assumed he'd follow. Spock just turned and walked down the corridor. He was right, McCoy was tagging along anyway, even if he could have sworn their orders included splitting up and investigating. The doctor hurried to catch up.

He was sure Spock had a list ready for why it was completely logical to travel together. Safety, different minds to come at a problem from a different angle, and it was a good thing he hadn't encountered that "Weeping Angel" last night, because having another pair of eyes would have been added to that list of his.

They stopped in front of a door. The door didn't give. McCoy sighed silently. More busting doors down. His joints gave a phantom ache at just the memory of the last time they had to do this. He was just a doctor, but at the rate they were going, he could turn over that blue tunic for a red one.

McCoy readied himself. "I'm getting too old to be busting doors down, Mr. Spock."
