Chekov sat up on the bed and gaped at the creature he had thought of as no more than a dog, "You can talk!" he muttered.
"Of course I can talk."
"Why didn't you say anything before?" Chekov asked.
"When your science officer brought me on board, your transporter did something to me. I do not know what it was but it rendered me without the ability to speak. The part that was here was irrational and brutal and I apologise deeply for the damage I have caused to both your crew and your ship. The part that was capable of logical thinking was with you. I aided you in your task and then your hardship in the hope of finding the other part of myself."
Chekov shifted in the bed and thought for a moment, "Thank you, for everything, your help made sure we survived in the cold." The words fell short and didn't seem like enough but it was the best he had.
"I am restored and now able to return to my home. This could not have been possible if you had not accepted my help. It is I who should be thanking you." Scotty was joined by McCoy who stood starring at the creature.
"Is there anything more we can do for you?" Scotty asked. Chekov let out a huge yawn which he was unable to stifle.
"I wish to return home. I have a family to look after, they will be worried." He said.
"If you follow me back to the transporter room, we'll have you back in no time." Scotty said.
"Will that not mess you up again?" Chekov asked with a frown.
"No, I have adapted. A natural gift of my people is to quickly adapt to change," said the creature. Chekov nodded.
"I'll see you soon then Fido." Chekov said.
"Maybe you will." Fido said, laughing at the pet name he'd been given, "Please Mr. Scott, lead the way and I shall follow you back to your transportation device."
Chekov watched the two walked away with a smile. Fido had been a decent companion and a decent friend. Although they'd not spent that long together, Chekov found that he would miss him. He looked over at the sleeping Sulu; at least he would always have a friend there too. It was a relief to be back home in the warm.
