Not Mine, Never Mine, Usual Disclaimers.
Spock could not explain as to why he did not want the Captain to be outside his quarters, the thought of the ball of fur not in his line of sight worried him as a bad idea for no logical reason. As Nyota attempted to push her argument further, they were interrupted by a small bark. The both of them turned towards the sound to see the pup looking at them.
'What is it?' Spock asked.
The pup drew up one paw and tapped one of the pieces carefully, then tapped an unoccupied square, then repeated the process.
'It's a legal move,' Nyota commented uncertainly.
Spock moved the piece before commenting, 'Checkmate.'
'This is weird,' she said, uncertainty colouring her voice.
'Captain,' Spock spoke slowly, fully addressing the pup, 'do you understand us?'
The pup bobbed his head up and down in a nod.
'I'm getting McCoy,' Uhura said, bolting for the door.
Spock looked at the pup for a moment before resetting the chess board.
'Care for a match?'
The captain quickly settled himself into Nyota's now empty position, moving the pieces with the ease of practice and those that were difficult to manoeuvre, he tapped and Spock would obligingly move the piece for him. About half way through the match, the door opened and predictably, the pup shot under the desk as McCoy walked in.
'Don't even think of hiding on me, you little scamp,' McCoy retorted, dragging the wriggling captain out from under the desk, 'I need to take another look at you, scans, blood work, everything.'
The pup threw the doctor a disgusted look and attempted to wiggle free, Nyota letting out a small giggle at the sight.
'Doctor, exactly what is it that you are looking for?' Spock enquired.
'Anything to explain how the captain of the Enterprise managed to turn himself into a dog. I will need to see him at least once a day from now on.'
The captain stuck his tongue out into a definite "yuck" face.
'Don't pull that face, unless of course you want to be this way forever.'
It never ceased to baffle Spock how quickly the captain would behave for McCoy, despite it being well known that Jim Kirk would rather suffer then allow his CMO to fuss over him.
The both of them watched as McCoy ran his tricorder over the pup, drew a blood sample and then gave him his hypo shot for the day. As soon as he was finished, McCoy took his leave, with Nyota following, claiming that she was behind in her reports. Spock knew that she was lying but said nothing of it, figuring that she was a little embarrassed to realise that the captain was so intimate with their arguing. The two of them passed the rest of the evening playing chess, like they used to do before Jim sprouted four legs and fur, not to mention the tail.
