Disclaimer: Stargate isn't mine. Dialogue taken from the episode Ethon. Daniel's thoughts in italics.
Daniel couldn't say what happened immediately after the Prometheus exploded. Whether he managed to get back to the cell under his own power or had to be dragged, he didn't know. He dropped down on the bench. From far away, he could hear Jarrod, but the words made no sense. The buzzing in his head was too loud. Sam. Teal'c. Mitchell. Dead. A sliver of hope sneaked around him. Maybe they had beamed off the ship. But, it was drowned out by the buzzing. Gradually, snatches of what Jarrod was saying broke through. "Daniel…. Sorry…. Shouldn't have…." He felt maybe he should say something. Tell Jarrod it wasn't his fault. But, he just sat there.
He heard footsteps. Boots. He kept his head down, staring blankly at the floor. He didn't care who it was or what they had to say.
"The loss of your people is regrettable."
Shut up, Daniel thought. Please, just shut up.
"The Caledonians would rather sacrifice themselves…."
"A year ago they launched a first strike against us…." Pernaux countered.
They started it, Mommy! Daniel dug his nails into his palms. He heard Jarrod's impassioned arguments. Just let it go. Let them kill each other. You can't reason with them. He would have said it, but opening his mouth took too much energy.
Jarrod pleaded with Pernaux. He used words Daniel would have used. That they needed to set aside differences to fight the Ori. He asked him to believe what Daniel had said about them.
You're wasting your time.
But, when Pernaux started recounting another of the priors "great" feats Daniel couldn't stand it. He lifted his head. The same lies, more people lost to the Ori. He couldn't just sit there and do nothing, could he? Sam. Teal'c. Mitchell. Dead. But, were they? Had they gotten off the ship?
"What choice do we have?" Those weren't the words of someone who was blindly following the Ori. They were the words of a man who wanted someone to convince him. As long as one person could be persuaded, there was hope.
Daniel stood up. Sam. Teal'c. Mitchell. Dead.He fought that down, and concentrated on the sliver of hope. Until he knew for sure, he had to hold on to that. Then, he started to speak. He had a job to do.
