John is walking down the corridor heading towards Rodney's lab. Teyla sees him and begins to walk besides him.

"John? I thought we were going to begin sparring again this morning?" she asks earnestly.

John looks slightly agitated, "Trust me, I was planning on it." He looks down at his attire. "See, I'm dressed for it, but Rodney said he had something important to show me and it couldn't wait."

Teyla smiles slightly, knowing that everything to Rodney is important. With John's quick pace, they get to the lab in no time.

"Rodney, this better be good. I do have other things I'd like to do today," John retorts.

Rodney notices that both Teyla and John are both in their workout clothes, "Oh. Sorry, but this is important."

He gets up and goes to a different computer and sits in front of it. Teyla and John stand behind him.

"Remember on the Daedalus, the device that the alternate me made to jump into different realities?" Rodney asks with excitement.

John straightens up and has a concern look on his face, "Yeeesss, and I already told you that making it would be a bad idea."

Rodney waves his hand to dismiss John's words, "Yes. Yes. But it looks like that I might have only helped to install it into the Daedalus."

"Well, that's good… I think," John responds with uncertainty.

Rodney rolls his eyes, "What I'm trying to say is that I believe the Ancients made it and then I must've came up with the idea of using it in the Daedalus."

John gets a sour look on his face, "And it was a bad idea." John pauses briefly. "Why would you think that the Ancients build it?"

Rodney looks at John and Teyla proudly, "Because I found it on the Ancient database. It's in one of the labs that we haven't explored in Atlantis yet and Woolsey says I can't check it out without you."

John sighs, "Fine. Let's go." He looks at Teyla. "Hopefully I won't be long. You can wait for me at the gym if you want."

"No, that is not necessary, I would like to accompany you if you don't mind," she smiles.

"I was hoping you'd say that. I'm still not comfortable with what this device can do," John stresses his point to Rodney. "And with Teyla with me, there'll be two voices of reasons," John says with a smirk.

"Oh, very funny. Ha ha," Rodney retorts sarcastically.

John and Teyla shares quiet smile.

"Let me go change first and we'll me you back here, Rodney," John says as he begins to leave the room. Teyla agrees and is about to do the same.

"Ah, come on!" Rodney protests. "It's just a quick look and I promise that I won't do anything."

John stares at him with disbelief.

"No, really. I promise," Rodney pleads.

John reluctantly agrees, "Fine!"

As they head towards the unexplored Ancient lab, Rodney turns his sight on John and Teyla, "So, when did you two start sparing again?"

"Ronon felt that since I was slightly out of practice, because I did not do any sparring while pregnant with Torren or since then, that I should practice with John," Teyla simply states.

John contorts his face and looks hurt by her comment, "That's not what he told me. He said that he thought I should have a different sparring partner once in awhile."

Teyla remains silent and gives him a sympathetic look.

--

It doesn't take them long to reach the lab. Rodney and Teyla go in first, but the room doesn't light up until John walks into the room.

"Huh. I'm surprised that it didn't light up when I walked in," Rodney whines slightly.

"Ok, we found the lab, I don't see anything, so let's go," John says with a nervous tone.

"What is wrong with you?" Rodney barks.

"I don't know. I just have a bad feeling about this place," John quietly responds.

Teyla looks at John with concern, "Maybe we should leave Rodney."

Rodney dismisses their apprehensions, "Just… Just give me a second to confirm that it's here or not."

They slowly walk around and find nothing. John decides to lean against a wall and a door to another room opens. It reveals the device that Rodney is looking for, but before Rodney can get close enough to see it, a force field surrounds John.

"Rodney?" John says angrily.

"I didn't touch anything! I swear." Rodney squeaks."It… It must've done it when you leaned against the wall."

"Well, do something," John snaps back.

"Right," Rodney says as he frantically looks around.

Rodney's computer pad begins to beep and Rodney quickly looks down, "Oh God."

"What?" Teyla asks with concern.

"I think it's charging up," he replies nervously.

"Rodney you must do something," Teyla says urgently.

"I'll try, but I'm not sure what to do," he timidly.

"What the hell?" John yells.

Teyla and Rodney both turn to look at John.

"What?" Rodney questions.

"The room is changing. I see trees around me. Can't you see it?" John replies.

Both Teyla and Rodney shake their heads no. John begins to double in pain and his body begins to phase in and out.

"Rodney, do something!" Teyla yells with desperation.

Teyla sees the look of fear mixed in with John's suffering. She feels so helpless and then he disappears completely.

"John!" she screams in agony.

Rodney looks up from his pad to see why she was screaming.

--

John wakes up and finds himself in a wooded area. He curses Rodney under his breath, but he's grateful to be alive. He looks himself over and regrets that he didn't bring any of his gear or his radio. He curses some more before he begins his trek to find some civilization.

Within an hour of walking, he happily finds a stargate and dials home. When he crosses the threshold, he doesn't even realize the subtle differences. The first person he sees is Rodney and the shocked look on his face.

John storms right up to Rodney, "Thanks buddy. I told you that it was a bad idea to check out that room, but would you listen to me? Nooooo. So, for the rest of the day, I'm going to ignore you, do some sparring with Teyla and relax in my room."

Rodney remains speechless and John hears a familiar voice come from the control room.

"John, you are alive?" Weir says with surprise.

John looks up and sees her, "Oh, crap."
