Rodney woke up on the ground of the jumper. It was cold and dark. He groaned as he picked himself up. His head was pounding.
Suddenly Rodney's eyes widened. Questions flashed into his head. He started to speak out loud to himself.

"Where am I? The jumper obviously.. But how - wait.. No No No No!"

He looked around him panicking. "The jumper! The Jumper is sinking!"

He stopped and frowned. "Wait.. What is this? Deja vu?.. Ohhh I get it. This is a dream. A dream! I'm going to wake up in bed."

Suddenly the jumper rocked. McKay grabbed on to the railing. The whale outside made a loud noise that filled the small jumper.

McKay grinded his teeth. "Nope. I'm not reliving this nightmare again. Time to wake up."

He slapped himself but it hurt. "Ow!" He looked around freaked. "Okay, okay. I shouldn't have felt that."

The air around him was getting colder. He could feel that too. It didn't make any sense. That meant this was real and if it was real he really did need medical attention. He went to the medical kit and pulled it down and prepared himself a band aid for his head wound.

After patching himself up he looked around trying to figure what this was all about. The whale once again made a noise.

McKay pointed to the ceiling where the whale would be outside. "Okay, okay. I'll play you're game Sam."
He picked up his table with annoyance and the whale made another noise.

McKay huffed. "Sadist whale. If this does turn out to be a very realistic dream you better not eat me."

After a while:

McKay continued to get frustrated at the small keyboard of his tablet. Suddenly the jumper lurched, hitting the bottom of the ocean.
McKay fell down at the impact and groaned. He heard the snapping of fingers behind him. He looked up and started to shake at who saw towering above him.
"No, no. This makes no sense. " McKay touched the side of his temple. "It's the concussion isn't it?" You're just a hallucination! Just like Sam was the first time. I'm not going crazy. You're not real. You can't be real.. Maybe I really am dreaming?"

The hand of the other reached down and Rodney got hoisted up by his jacket.
"Do we feel real now?" His other self questioned with an eye roll.

McKay winced at hearing his own voice replying back at him. It gave him flashbacks of Cadman.
He looked around the tiny jumper for help which the jumper couldn't provide, then asked. "What are you?"

His other gave him a look like he was stupid.. He waved his hands about as he spoke. "Hmm.. Lets think.. What are we?"
He put his palm up and looked at it. "A wraith? Nope."

McKay frowned at him annoyed and crossed his arms. "You know what maybe I am going crazy. This whole trip down memory lane is crazy."

The other just raised an eyebrow at him then smirked. "Crazy like a fox."

McKay rolled his eyes at him. "Are you going to help me out of here?" He asked as he returned to looking at the crystals.

"Don't you mean help so we can both get out of here?" The other crossed his arms, looking at him.

Rodney frowned at him strangely. "You're not real. You can go anywhere you want." Rodney pointed to himself. "Yours truly however can't."

The other frowned back at him. His mouth slanted. "We're real. Not, not.. real."

Rodney grinned his teeth frustrated as he continued to work on arranging the crystals and connecting cables.
"You're still not helping. Make yourself useful if you wont leave."

The other rolled his eyes and made his way over to the bulk head door to check the sealing as water was starting to leak in he dived in.

After a while of evaluating the bulk head door he came back up.

"We've got micro fishers." The other said pointing a thumb to the bulk head door. He was soaking wet and shivering.

McKay looked over from his work and looked him over. Noting his condition oddly. Even hallucination Sam didn't shiver. "You okay?"

"Could use some heat.. Don't want to get hypothermia."

McKay nodded. "Right, right." He input the code watching the energy power timer slip away.

"We should also raise the pressure in here." He added. McKay nodded and did that as well.

They held their noses and popped their ears as the pressure increased.

The other sat next to him and leaned over his shoulder. "Thanks for asking."

Rodney looked up. The other was looking at him strangely, but in a kind way.

"I uh,.. Sure. No problem." Rodney responded. Not used to hearing the word 'Thanks'.

"Not many people care about our comfort. It means a lot."

Rodney looked at the other Rodney and frowned feeling sympathetic for him. Which was a strange emotion to Rodney.

"Um can I ask something?.." Rodney asked, his fingers twitching in thought.

The other tilted his head, looking at him. Wondering if this was the perfect opening to distract himself from trying his stunt with the jumper that was doomed to fail.
"Sure. What do you want to know."

"Who are you exactly?"

His look alike smirked and pointed a finger. "Now that's an interesting question."
