Meanwhile, on the planet, the team were searching the area for any clues of an antidote. So far, nothing.

"There has to be something here." Daniel said.

"How long have we got?" Jacob said. Castleman looked at his watch.

"3 hours." Castleman said.

"Then we'd better hurry." Jacob said. They searched the area some more. They found an injured Jaffa, Teal'c went upto him.

"Did you work for the Goa'uld who worked here?" Teal'c said. The Jaffa laughed.

"My Lord's work is done, no doubt the human is dying, just as my Lord planned." The Jaffa said.

"What about an antidote?" Daniel asked.

"Why would I tell you?" The Jaffa sneered.

"Because we'll ease your suffering if you tell us." Castleman said.

"The antidote…is one of the rarest kind. The human will die before you find it." The Jaffa said. Castleman had had enough.

"We don't have time for riddles." Castleman said. He went up to the Jaffa and grabbed him by the scruff of the neck.

"Major Castleman, stand down." Jacob ordered.

"No, he's not going to tell us if we just ask, this is the only way." Castleman said.

"He's right." Daniel said. Then he turned to the Jaffa. "Tell us what we want to know."

"It is the blood of one who used to be, but is no more." The Jaffa said. Then he died.

"Great, so the antidote is the blood of a dead person?" Sergeant Morris said.

"It's a riddle, we need to figure it out. Jack's life depends on it." Daniel said.

"Let's go." Jacob said. They all went toward the gate.

The alarms in the SG-C were blaring as the gate began to turn.

"Unscheduled off-world activation." Richards said.

"Who is it?" Hammond said. The gate opened behind the iris. They got a code through.

"It's SG-1's iris code." Richards said. Hammond entered his command override to open the iris.

"Open the Iris." Hammond ordered. The iris opened. Hammond went to the gate room just as they came through. "Did you get it?"

"Not exactly, we got a clue as to what the antidote is." Daniel said.

"A clue…what kind of clue?" Hammond asked, looking puzzled.

"A riddle, 'the antidote is the blood of one who used to be but is no more'." Daniel said.

"The tricky bit is working out what that means," Castleman said.

"That refers to someone who is dead." Hammond said.

"No, it's not that simple. It has to be more complex." Jacob said.

"How is O'Neill?" Teal'c asked.

"He slipped into a coma 2 hours ago," Hammond said. "And I think that I should warn you. Everyone is in trouble with the NID. Major Carter, Dr Fraiser, SG-3 and I are in for court-martials, Teal'c, you are to be sent back to Chulak and Dr Jackson, you are to be kicked off the program."

"What for?" Daniel asked. Then Simmons walked in.

"The list of offences is endless. General Hammond's offences include unlawful imprisonment and insubordination, Major Carter's offences are insubordination and threatening to kill an NID official, Dr Fraiser's offences are insubordination and striking an NID official, SG-3, Teal'c and Dr Jackson for insubordination, need I go on?" Simmons said. Then he turned his attention to the Tok'ra. "I can come up with adequate punishment for you two."

One problem Colonel, we don't answer to the Vice-President and therefore we don't answer to you." Jacob said. He lowered his head and allowed Selmak to take over.

"We answer to the Tok'ra." Selmak said. Then something hit Daniel.

"The Tok'ra, that's it. It's not the blood of a dead person, it's the blood of a former host." Daniel said.

"Of course, someone who was a host but isn't anymore. They are rare, but who?" Jacob said. Daniel and Teal'c were obviously thinking the same thing.

"Major Carter!" They said together.

"Let's go." Hammond ordered. They all rushed to the infirmary. The NID followed. They saw Sam next to Jack and Dr Fraiser next to her.

"What's going on?" Fraiser asked.

"We know what the antidote is." Daniel said.
