Sam awoke to a splitting headache and a sore neck, although she had no idea how either had got there. She rolled over onto her side and stood up. She stumbled to the door and turned the handle. Locked. She reached into her pocket for the keys, but came out empty handed. She tried the handle again, this time pulling harder, but the door was locked solid. Sam began banging on the door and shouting, "Hello?" There was no answer. Sam banged on the door even harder until she heard her own name being called from the other side.

"Sam?"

"Janet!" Sam yelled back, "Is that you?" Sam saw the door handle move.

"Yeah, Sam, it's me. Are you okay? The door's locked."

"Yeah, I know. I don't have my key though. I can't get out!"

Hammond stepped forward. "Major, stand back from the door, we're going to try to break it down." After hearing the all clear from Sam, he nodded at Teal'c. Teal'c kicked the door near the lock, but to no avail. Twice more, and the door began to rattle. A fourth kick brought the door swinging violently back on its hinges. Janet ran into the lab.

"Sam, are you okay?"

"Uh… I think so. I got a headache but that's all. What happened?"

"You don't remember?" Janet asked as she moved to inspect Sam's head. She paused. "We think Colonel O'Neill's a Goa'uld." Sam's eyes widened as memories suddenly raced back.

"Oh my God! Daniel! He said he was going to see Daniel!" Sam pulled herself forward, only to be stopped by Janet.

"It's okay. Daniel's going to be fine. He's just been sedated, that's all. Sam, there's a lot of blood here," she continued, looking at Sam's head, "we'd better get you to the infirmary."

Sam held on to Janet's shoulder and with her help made it across to the door. She looked up to see Jack stood behind Hammond, a repulsive sneer across his face as he lifted his Zat and pointed it at the back of Hammond's head.

"General!" Sam yelled. Hammond spun around and fell to the ground as the electricity rushed through his body. Teal'c lunged at Jack, pushing him to the ground. Jack punched Teal'c in the ribs, and then again in the face. Teal'c stumbled backwards in to the wall, and Jack sprung up and flew at him. The two men fell onto the floor and Jack landed another punch in Teal'c's face. Teal'c fought to push Jack up and Janet and a still disoriented Sam grabbed Jack from behind and pulled him up. Teal'c rolled over and grabbed Jack's Zat which had fallen during their struggle. Jack threw his arms back to hit both women simultaneously and, seeing the Zat, manoeuvered backwards as Teal'c fired a shot that missed Jack and hit the wall. Janet struggled to stand up and landed a blow in the back on Jack's knee that sent him tumbling backwards. Janet threw herself over Jack and, with Sam's help, held his arms down. Jack resisted for a few seconds. Suddenly, his body went limp and, for the third time in two days, Sam saw the blinding light fill the corridor. As Sam and Janet shielded their eyes, Teal'c pointed the Zat in Jack's direction and fired an educated guess at his position. The light faded and Teal'c saw that his guess had been correct. He moved over to help Sam and Janet move Jack's unconscious form to the infirmary, whilst two passing SFs helped the General up.
