Cameron walks into Daniels office where Daniel is busy cataloguing artifacts
Cameron: Jackson. I thought I told you to get some sleep.
Daniel: Yeah, yeah, 10 more minutes, I gotta get this down.
Cameron: You said 5 more minutes an hour ago. You need some rest. I want you bright eyed and bushy tailed for our three o'clock mission start.
Daniel: Three am? Why?
Cameron: It's the original 'Gate Lag. P2J-827's Stargate is in a different time-zone. General Landry wants us to negotiate an alliance with them.
Daniel: Okay, 10 more minutes. I promise.
Cameron leaves. Daniel puts down his pen and picks up an artifact. He sees a small symbol on the side. He touches it and it glows blue. Daniel frowns as the light glows brighter. The light grows so the entire room looks like it is glowing. It flashes almost unbearably bright and Daniel is thrown back into his seat. He yells. Then he gets up and laughs. He looks down at his clothes and fingers and gets confused, but feels reassured when he feels his face.
Daniel: I'm back? I'm back! Ha ha!
Cameron comes in
Cameron: What's happening?
Daniel: I'm Daniel Jackson, SG-1.
Cameron: I know that.
Daniel: I've come back! I always thought that Earth was destroyed, but here it is! After all these years…
Cameron: Jackson, I saw you two minutes ago.
Daniel: No, no, I've been gone for two years.
Cameron is confused and Sam comes in.
Daniel: Freaked out of his brain No… No!
Sam: Daniel, what's happening?
Daniel grabs a pistol and shoots Sam in the shoulder.
Sam: You shot me!
Daniel: You're already dead!
Daniel grabs his head and rolls to the ground, unconscious. Cameron catches him just before he hits the ground. Close up of Cameron, then Sam.
