Teyla sat up in bed, struggling to grasp the unraveling threads of the dream that had been so vivid only seconds before. There was a man, one she knew and yet didn't, and the frightening feeling of suffocating. Her hand went to her throat, fingers ghosting over her pulse point, feeling the pounding of her heart as leftover adrenaline coursed through her body.

Adrenaline…

Between one heartbeat and the next she was out of bed and through the door of her room, pounding bare-footed down the corridor. She couldn't say for sure what was driving her to the infirmary, or what she expected to find when she got there. She only knew one thing, one absolute fact that made no sense at all, but alarmed her beyond reason.

The dosage was much, much too big.

She rounded a corner and spotted Ronon coming from the other direction, no doubt on his way back from a late-night raid of the kitchen. He registered the urgency on her face and changed course, wordlessly falling into step with her. "Doctor Beckett is in danger," she panted.

Ronon didn't bother asking questions, but simply increased his speed. His long, loping gait carried him ahead of her and he burst through the infirmary door seconds before she did.

Teyla was shocked to see Carson Beckett, cast and all, standing in the center of the floor. He was struggling with another man, and both their fists were clenched around a dripping syringe. She took a step forward, but before she could intervene Ronon slid his gun from its holster and took aim. "No!" she cried, but a wash of light swept over both combatants and they slumped to the ground.

"It's set to stun," Ronon said, sounding somewhat offended.

"His back is injured," she shot back, moving to the doctor's side. "Call Colonel Sheppard." Teyla pulled a blanket from a nearby bed and covered Beckett's scrub-clad body. She didn't know what else to do for him and hesitated to touch him at all for fear of hurting him

"Sheppard's on his way. I called a medical team, too," the big Satedan said, crouching down beside the still form of the fallen nurse. "This guy's out cold."

Teyla rolled the other man onto his back and carefully secured the syringe. "I do not know this man."

Footsteps sounded in the hallway, and Sheppard suddenly burst into the room, shirt untucked and hair even more disheveled than useful. His eyes moved from one still form to the other and grimly muttered, "Dunne."

"Done?" Teyla frowned, confused.

"His name. Dunne. Also known as Suspect Number One."

Carmen arrived and took charge of the unconscious men. After a brief examination, she ordered both Carson and Rick to be taken for scans. Jeff Dunne was deposited on a bed, and Sheppard immediately placed him in restraints and set Ronon as a guard.

Teyla handed the syringe to Carmen. "They were fighting over this, but I do not know what is in it."

Stepping to the open drug cabinet, Carmen ran her eyes over the contents until she found an empty vial. She double-checked the level in the syringe and blanched. "It's epinephrine," she said, clutching the vial in her fist. "Almost thirty mils."

"Fatal?" Sheppard asked quietly.

"Twenty times over," came the answer. "Please tell me what the hell happened here tonight?"

Teyla opened her mouth to answer, but suddenly realized she wasn't sure.

"This guy was going after Beckett," Ronan cut in.

Sheppard raised an eyebrow. "Teyla, you agree?"

"I…am not sure," she admitted. "They were struggling over the syringe, but I don't think Dunne was trying to harm Doctor Beckett."

"Why not?"

For a moment she was at a loss, and then suddenly she understood. "I had a dream."
