Peter DeLuise makes his traditional SG series cameo in an episode he directs as the technician being replaced by Colonel Telford. Peter's character's name was also Peter.

Franklin: Just over 90,000 liters.
Eli: 91,046. Ish.
Scott: Go, Math Boy.

Eli: I don't think the showers use water. They just spray a sort of mist that you stand in and it sorta beads up. There's one in a compartment off the crew quarters.
Scott: How do you know all that if you haven't tried it?
Eli: How do you know I haven't tried it?
Scott: Oh, we know.
Eli: Thank you, Lieutenant Rosegarden.
Chloe: No, he's right. You're worse than he is.
Young: Wow, you can tell them apart.

Becker: My assignment, sir?
Young: Recipes, Becker. For the love of God, recipes.

Chloe: You don't have to follow me around.
Eli: What do you mean?
Chloe: I mean that I'm okay.
Eli: Oh. Thank God you said something, because I thought you were following me around and it was about to get awkward.

Chloe: I don't even know what to do with myself, Eli. I'm the last person who should be here.
Eli: I'm second to last.
Chloe: You're underestimating yourself.
Eli: So are you.

Young: Okay, I get it. Who can I bring in to help.
Rush: Honestly, it may take longer than we've got to bring someone else up to speed.
Young: Volker it is.

Marine Sgt. Spencer: What's going on, Eli?
Eli: You mean right now?
2nd Lt. Vanessa James: Don't be an idiot.
Eli: Wow, you must be getting to know me because I respond really well to that.

Volker: Uh, Dr. Dale Volker. I'm 34 years old. Uh, despite you may or may not have heard, from a certain Scottish person, I like to think that I'm a pretty fine astrophysicist. I mean, they don't send you to work on solving the mysteries of the universe on other planets if you're a hack, right? So... that's all I have to say. And we can't all be Mozarts, right? Some of us are... Salieris. Not that there's anything wrong with that. I... I like Salieri. I find his music is, uh... it's uh, it's soothing. I'm not suggesting that he's Mozart, either. Although Mozart did go a little nuts, didn't he? All right, I'm done. He's maybe a Schubert at best. Or an Elgar. I'm done, Eli.

Young: Eli?
Eli: I put a kino into search mode and sent it into un-pressurized areas of the ship looking for an active console somewhere. Nothing yet. Also, I was looking into seeing if there was any way to integrate the shuttle's power with the ship's system?
Young: So you're working the problem?
Eli: Yeah.
Young: Does the computer-hacking dropout have to save our asses?
Eli: The dropout is still here.
Young: Or are you going to get your heads out of yours?
Franklin: The shuttle idea's pretty good.
Volker: Yeah, there might be a work-around.
Young: Well, let's do that. Thank you, Eli.
Eli: Uh, by the way, it's... MIT dropout.
Young: You want, you want a gold star for that?

Rush: Colonel, about our previous conversation.
Young: Rush, no need to apologize.
Rush: I wasn't about to.
