The Reds and Blue returned to the canyon. Washington tried to figure out how Delta was alive, but the AI said he didn't know. Wash decided to try and figure it out as soon as possible. He knew Santa had gotten the AI, but not how. For that, he was suspicious; he knew something was up with that guy. He couldn't just have Delta poof out of nowhere.

"We're back," Tucker stated.

"Finally," Grif sighed in relief, parking the warthog and getting out, dropping onto the grass and staying there. Sarge also got out and looked at Grif. He then proceded to kick him in the side. "Hey!"

"There you are, sleeping as soon as you get the chance!" Sarge shouted at the orange guy. He turned around, "Now if you'll excuse me, I have to apply this headlight fluid!"

"How did Santa even get that stuff?" Tucker asked.

"We don't know," Washington replied. "We also don't know how he got Delta."

Tucker turned towards Wash, "You never showed us what Santa gave you. What is it?"

"Uh... nothing!"

"..Right." Tucker shook his head, walking towards Blue Base. Wash sighed in relief.

"Hey, where's Doc?" Donut suddenly asked, looking around the canyon. "He was here when we left."

"Donut's right: he isn't anywhere!" Simmons exclaimed, also glancing around the canyon.

"That is not a good thing, is it?" Caboose asked. "Is it a not good thing, or a not a not good thing? Is it an opposite of the opposite of a not good thing?"

"Uhh.. What?" Washington asked. "Maybe?"

"Oh.. That's not good."

"Yeah.. Let's find Doc, then," Washington began to search the canyon.

"If we don't find him, does that mean we have to take another road trip?" Grif asked.

"No. If Doc wants to leave, he can leave," Washington answered.

"Okay, good, because I was not gonna drive that far again!"

"It would be wise to go after him; it isn't good to not have a medic around," Delta popped in to say.

"He was never a good medic anyways," Epsilon said.

"Besides, he was always really annoying," Grif added.

"It would be more helpful to get rid of him than to keep him," Simmons finished.

"Jingle bells, jingle bells, jingle all the way!"

"What the hell?" Epsilon asked.

"Oh what fun, it is to ride, in a one horse open sleigh! Hey!"

"WHO IS SINGING!?" Washington shouted.

"Jingle bells, jingle bells, jingle, jingle all the way!"

"Wait...," Epsilon held up a hand, "I recognize that voice..."

"Oh what fun, it is to hurt, the ones who disobey!"

"Is that who I think it is?" Wash asked.

"Crashing through the snow, falling on your knees, let me help you up, to perform surgery!"

"Yes, I'm pretty sure it is," Epsilon answered.

"Watch the blood fall out, pouring on the floor! Finish the operation, then just push you out the door!"

"Dr. Grey?" Wash called out.

"Jingle bells, jingle bells- oh, Washington!" Dr. Grey ran over. "Did you like my song?"

"Uh.. It was.. Interesting," Wash answered. "What are you doing here?"

"I heard your medic left, so I came to assist!" Dr. Grey told him.

"Wait.. How did you hear about that?"

"Oh, don't be silly! I know everything that goes on with you guys!" Dr. Grey laughed. "Everything."

Epsilon whispered to Washington, "Stalker!" He turned back to the insane doctor, "So you're staying? With us?"

"Yup! I'll be with you forever! Oh, I better unpack!" Dr. Grey ran off towards Blue Base.

"WHY IS SHE HERE!?" Tucker yelled from inside.

"APPARENTLY STAYING FOR A WHILE!" Epsilon answered.

"WHY!?"

"SHE SAID WE NEED A DOCTOR OR SOMETHING!"

"Should we go in their with him? Just incase?" Wash asked.

"He's fine," Epsilon assured him.
