If One Thing Changed: Doppelganger

"I was just about to come to see you but I was not sure you would want To see me." John Sheppard said standing in his doorway as Teyla Emmagan quickly threw her arms around John's neck and he slowly wrapped her in a hug, stiffly and awkwardly. After a couple of minutes, John guided her to his bed and sit her down on the edge of it, and knelt down in front of her. Teyla stared down at her clasped hands, John reached out and tilted her head upwards so they could look into each other's eyes.

"I tapped my earpiece trying to get in touch with Kate before I realized that she would never answer.." Teyla said a couple of tears slipping down her cheeks, John quickly wiped the tears away from her cheeks.

"I'm so sorry that I caused your friend's death. I never want to bring you hurt, I would give anything to make you happy." John said as Teyla ran her fingers into his messy hair and pulled him closer to her.

"It's not your fault, it's that alien entity," Teyla said grabbing the back of his head and crashing his mouth to hers.

"I'm the idiot that touched it," John said the pain still clear in his eyes.

"Might be so but you are my idiot," Teyla said kissing him again as she pushed him back onto the bed and straddled him. John started untying her top and let it drop to the ground, Teyla quickly started undoing his Garrison shirt. Soon enough their clothes littered the ground.

"We should have done this sooner," John said as he slid inside of her and started to thrust in and out of her as Teyla dug her fingernails into his back and ran his hands up and down his back.

"Harder," Teyla said through a whimper, a few minutes later, and a couple hard thrusts later they both reached their release and both let out cry's of pleasure while doing so. John went to pull out of her when Teyla stopped him.

"No stay," Teyla said pulling him close.

"I'm going to crush you." He said kissing her, as she used her fighter strength to flip them so that a John was underneath her and she curled up on top of him, with John still snugly inside of her.

"I love you." She said kissing his chest.

"I love you too." He said kissing her. Almost 2 months later Teyla sit beside John's bedside, it seemed that the nightmare had hit John the hardest and it wasn't letting go just yet. They had returned the alien space rock after John had fought it and freed McKay and they thought himself, but 2 months later John was still in a coma. Teyla sit in the reclining chair that Ronan had found somewhere with her hand intertwined with John's. She was lost in her thoughts as she stared at John, she took their hands that were joined together and laid the intertwined hands against her slightly rounded stomach.

"I need you to come back to me my love, it is not just you and I any longer," Teyla said it was then that she felt movement against her stomach. She looked down and for the first time in almost 2 months, John's hazel eyes were staring back at her. He tried to speak but started coughing, Teyla quickly grabbed a cup of water and got him to take some sips.

"I need to get Jennifer," Taylor said going to stand but Teyla kept a tight grip on her hand.

"Wait before you go, we're having a baby?" John said his eyes got misty as did Teyla's.

"Yes my love, I found out a few weeks back we are to be parents." She said as he tugged on the edge of her hair and gave her a deep kiss.

Finally, a week later John had finally gained enough strength that Dr.Keller released him. After much discussion, it was decided that he would stay in Teyla's new quarters. Because of the upcoming arrival, she had been granted larger quarters which led to extra space for the small family.

"Here you go, my love," Teyla said as she helped John quickly change and lay back on the larger bed. As she helped him lay down on the bed she could see the thoughts already forming in his mind.

"I did not do it on my own, Ronon and Halling helped trade for the bed and then help to sit it up. Halling also made this for our son or daughter." Teyla said getting up and packing a cradle over to a bedside for John to see. John and his fingertips against the etchings on the cradle.

"Halling said that it tells the story of the family thus far," Teyla said giving John a kiss as she put the baby stuff away in the corner of the room.

"We're so lucky," John said as he pulled Teyla down to the bed and curled his arms around her, and rubbed his palm over her growing bump.

"We are my Love," Teyla said cuddling into his arms more.

"Marry me," John said kissing her forehead.

"Yes." She said leaning up and giving him a deep kiss, they then pulled away from each other John dug around in his nightstand and looked for the box he had asked Ronon to put there he finally found it and opened it.

"This was my mother's and before hers, it was my grandmother's, and so on and so on. Teyla Emmagan daughter of Tagan, will you do me the honor of being my wife."

"Yes." She said as he slid the ring onto her finger. He then held her close, the afternoon sunlight catching the engagement ring as Teyla laid her hand beside John's where their baby grew inside of her.
