Sheppard glanced around at his team; Lieutenant Ford stood uneasily, excited to be headed through the Gate but concerned about what they would face. Teyla was calm, hands easy on her P-90 as she looked back at him. McKay was, for a brief moment, silent. As he looked at Sheppard, though, his mouth opened, "Well, what are we waiting for? I thought we had a mission to go on?"
Sheppard smiled, "Let's go then." He reached up to activate his radio and request they dial the gate when a sound not unlike thunder ripped through the room accompanied by a strong gust of wind. Sheppard didn't think, he moved in front of Rodney, lifting his P-90, looking for the threat.
"Oh my god," Rodney said, his hand appeared over John's shoulder, pointing at the gate.
In the middle of the Stargate was a slowly growing vortex. It was blue, olive green and black, with purple lightning flickering from its depths. "Doctor Weir," Sheppard asked, "do you see it?"
"I see it, Major," Dr. Weir replied.
Another crack of thunder shook the Gate Room, followed by sound. A high wailing noise, like an alarm was first, a three tone cry of warning and imminent danger, then a computer voice speaking a language Sheppard didn't understand. Finally, human voices, making Sheppard glance at Ford, who had dove in front of Teyla
"Justin, get back! You have to take a pod." Someone shouted. From his voice, John thought he was an older guy, probably terrified out of his mind.
"I got it, Merlon," someone else responded; young, male, brave and reckless no doubt.
"Justin, the station is going to blow in less than thirty mirtaks. You don't have time." Merlon said.
"Would you shut up and let me focus," Justin replied, exasperated. Silence, save for the alarms and the crackling, roaring sound of the vortex, descended.
"McKay, what do you think that is?"
"A swirling vortex of doom?" McKay offered, "If you would move so I could scan it."
"No," Sheppard replied, his gut clenching. "You do your tests behind me, from here. We don't know if that thing is dangerous."
"Oh, for heaven's sake," McKay growled. Then he ducked around Sheppard and advanced on the portal, scanner in hand.
"McKay!" Sheppard snapped and followed him, "Stay back from it. I do not want to lose someone right in the middle of the Gate Room!"
The alarms altered, from three part harmony to two part dissonance making Sheppard wince and Rodney wave his scanner at the vortex insistently. "Got it Merlon," Justin crowed triumphantly, "I told you. Now let me do something about these fires."
"All right," Merlon replied, "good job, Justin."
"I learned from the…aw hell," Justin said.
Whatever else he was about to say was overridden by a computerized voice in a foreign language.
"Yeah, yeah," Justin muttered when it was done. "Shit."
"Justin!"
A building roar and a scream made John pull Rodney back and down moments before fire began to flicker out of the vortex. John watched it warily, then the roar reached its peak, making him cover his ears, and something on fire was flying out of the vortex. It hit the ground and started to roll. John blinked, and then realized it was a human, trying to roll out the flames. He didn't even think he was out of his tac vest and pack in the time it took him to stand, he had a blanket from his back in the three strides it took him to cross to the person and he quickly began to slap the flames with the fire-retardant material.
When the fire was out, the man lay on his side for a moment, and then rolled on his back with a moan. John caught a quick impression of blue-black hair and blue eyes before the eyes closed and he relaxed. John knelt and reached for a pulse, careful of the burned skin, and found it, weak and unsteady. He lifted his hand to his ear, "Doctor Beckett, we need you in the Gate Room for a medical emergency."
"What?" Dr. Beckett replied, his brogue thick, "But you haven't even left yet! How can you have a medical emergency if you haven't left Atlantis?"
"I'll explain it to you when you get that here with a medical team," Sheppard replied tightly. "Have someone set up a burn unit."
"Burns," Dr. Beckett repeated. "We're on our way to the control room now, Major."
"Not the control room, the Gate Room, as in, I have a kid in need of medical attention lying on the ground in front of the Stargate." Sheppard snapped tightly.
"Right," Dr. Beckett said. Moments later, he led the medical team in and Sheppard backed off. "What happened?"
"He came through a vortex on fire," Sheppard replied.
Dr. Beckett nodded and turned to the young man and the medical team. Sheppard glanced around, Ford and Teyla were still on the stairs, although Teyla had Ford backing away as she spoke to him. Sheppard considered it a moment and decided that the Athosian leader was giving Ford a piece of her mind for his attempt to protect her. He looked away and found McKay standing close to the Stargate with a device in his hand that he was frowning at. Sheppard moved around the medical team on his way to McKay. A quick glance showed Markham and Stackhouse among the marines nearby. "Sergeant Stackhouse," Sheppard said, "you and Markham provide security for our guest. I want one person with him unless or until I tell you otherwise or Doctor Beckett needs privacy for a medical procedure."
Stackhouse saluted and Sheppard nodded. The good thing about having Marines to boss was that they were very good at following orders, especially during the aftermath of an unusual occurrence. "Major Sheppard," Dr. Weir called.
Sheppard turned and looked up at the team expedition leader, "Yes, Doctor Weir," he replied.
"My office, please," Dr. Weir said before heading back into said office.
"Yes ma'am," Sheppard said as he started back towards the stairs, over his shoulder, he added, "Let Doctor Weir and I know what happened as soon as possible, McKay."
He didn't actually understand McKay's response, but Sheppard would bet his last bars of chocolate that the man had been as unflattering to him as he always had been.
