In no particular order:
3. From "The Return":
The phone conversation:
Rodney: I don’t – I don’t want to use the term lonely, but...there are certain people who ...I miss.
Rodney: You? You--I’m talking to on the phone right now and having dinner with tomorrow, so not so much, but other people – people who I may never see again. Like, even Elizabeth – she hasn’t returned any of my calls.
Aw, team love! Rodney misses everyone. And slashy love! John, you smug little thing, you. Of course Rodney misses you. Even though he's having dinner with you AGAIN, and talks to you constantly the phone. (You just know Rodney called John three times a day).
2. From "First Strike":
While Rodney and Radek are inspecting the warheads-
Rodney: Yeah. It’s good to go. This is a bad idea, isn’t it?
Radek: We could tell them they’re not ready – you know, there’s a fault with the guidance system or something.
Rodney: I thought about that. They’re going to have guys here to contradict us pretty quickly.
Radek: Yep. But we’re here alone. We could make them not ready.
Rodney: They’re building an armada, Radek. I saw them. They showed me the pictures. I’d feel pretty stupid if we break this thing, only to have the Replicators show up and destroy the city.
I love, love, love the fact that the two of them are seriously discussing sabotaging military equipment. There's not a whole lot of civilian/military conflict in SGA but when it does happen it makes me very happy.
3. And of course, from "Echoes" (I loved every line in that ep)
for the sheer silliness-
Rodney: Ah. There you are. You are not going to believe this. I’ve been monitoring Sam on the underwater scanner ...
John: Stop calling him that.
John: It’s creepy!
Rodney: No it’s not. Look ... (he points to the screen) ... here he is, circling the city. He’s been doing it for a while. Won’t leave.
John: You didn’t feed him, did you?
Oh, John, you big silly thing you. I burst out laughing at that. Plus, of course, John getting all jealous over the 'Sam' thing. *g* How cute is that?
