He had stormed off like a child. Stomping down the hall as though claiming his turf as he retreated to his office. O'Neill slammed his office door behind him and began to pace the room as he tried to resist the urge to ram his fist into the wall...

Two floors down, Lt. Col. Carter was toiling away over the exam table where she delicately tried to finish the last steps in completing the antidote...

Above her, Jack looked down on her from the observation room with Daniel beside him as they stood on pens and needles-- knowing just how volatile the experiment below really was.

"I hope she's as good as my Sam." Jack said crossing his arms over his chest.

"Actually..." Daniel said with a smirk. "She does stuff like this all the time."

"So does mine." Jack said taking a step back from the window to sit in a chair behind him. "Sammie never listens to me...every time I turn around twice she's getting herself into something else..." He said leaning forward on his knees. "But what can you do, uh?"

Daniel turned back to the window and looked back at Sam. It was awkward to hear Jack talking about Sam so...freely. Normally any conversation concerning her would consist of one-word answers and cliché military babble about honor, duty and unit cohesion. But this version of Jack clearly knew a different side of her, and he wasn't afraid to show it.

Noticing his sudden change in behavior, Jack realized that, unlike his best friend Daniel who was responsible for him owning up to his feelings, this Daniel wasn't used to being put between him and Sam...and he wasn't about to try and talk about it.

"Sorry," Jack said standing and walking back to Daniel's side.

"About what?" Daniel asked crossing his arms and wrinkling his forehead as he looked over to Jack.

"I keep forgetting we aren't supposed to talk about that."

"About what?"

"Me and Sam."

"Well, it's just..." He said drifting off to look down at Sam in the lab below, he started to speak again but stopped when Sam suddenly dropped to the floor unconscious. "SAM?" He screamed through the glass. "SAM!" He yelled once again. He looked over his shoulder to see Jack—but he had already ran from the room...

IN O'NEILL'S OFFICE...

The alarms rang throughout the base. At first he thought it might be an incoming traveler, but Daniel's voice caught his attention as he spoke over the intercom through the alarm and with in seconds O'Neill was running down the corridor toward the lab...

Jack raced down the flight of stairs to the entrance of the lab that was on the floor below the observation room where he had been watching Sam. As he rounded the corner he slammed in General O'Neill who was also racing to the lab entrance.

"What the hell is going on?" O'Neill demanded as he swung the door open and entered the room.

"She just collapsed!" Jack said following him into the clean room that separated them from the actual lab where Sam lay unconscious.

As they reached for the environmental suits, Daniel ran in behind them.

"There's no time for that!" Daniel yelled as he headed for the sealed door of the lab. "The suit won't protect her from the virus!" Daniel yelled as he pulled the door open-- before either Jack had time to register what he'd said they were running after him.

The three men hurried into the room. Daniel took Sam by the shoulders and Jack took her feet as they carried her to the door.

O'Neill followed them, but as Daniel pulled Sam through the doorway there was an explosion behind them. The force sent all four of them to their knees and the virus spread into a cloud that filled the room.

Without hesitation, Jack all but threw Sam onto Daniel and slammed the door—locking him and O'Neill in the lab.

Daniel lay on the floor of the clean room with Sam in his arms. Looking up to the door he saw Jack and General O'Neill looking back at him—their fates were sealed.
