(McKay and Harmony are waiting while Sheppard finds another route around the river. Harmony takes a power bar from the backpack that Sheppard left)
McKay: Where'd you find that?
Harmony: John's bag.
McKay: That's not yours!
Harmony: I'm hungry.
McKay: Well, you can't just take it like that!
Harmony: When I'm hungry, I eat.
McKay: What's gonna happen when Sheppard finds out?
Harmony: Well, he's not going to now, is he?
McKay: Well, yes he is 'cos I'm gonna tell him.
Harmony: I wouldn't do that if I were you.
McKay: Yeah? Or what?
Harmony: I'm the queen.
McKay: Not yet, you're not, little sister.
Harmony: Trust me, you don't wanna be on my bad side.
McKay: Right, what ya gonna do? Have me beaten?
(Harmony stares at McKay, without saying a word)
McKay: Alright, princess, just hand it over.
(Harmony hands him an empty wrapper)
McKay: Oh, now you're in trouble. You just wait until Sheppard gets back here, 'cos he's gonna-
(Sheppard comes back)
Sheppard: Alright, I think I found a place for us, to, er...
(Sheppard notices the empty wrapper in McKay's hand)
Sheppard: Is that my power bar?
McKay: (Points at Harmony) She stole it!
Harmony: I did not!
McKay: What?! You sure did, tell him!
Harmony: I would never do such a thing.
McKay: The second you were gone, she went into your bag!
Harmony: You're a liar! You are a lying liar!
McKay: Oh please! Who you gonna believe?!
Sheppard: Well, if she stole it, Rodney, how come you've got the wrapper?
McKay: Wa, erm, I was trying to take it back from her and then she wolfs it down and hands me the wrapper!
McKay: (To Harmony) OK, you better come clean, brat!
(Harmony starts crying. Sheppard hugs her)
Sheppard: It's okay, sweetie. Sometimes, he makes me cry too.
(Harmony makes a fist at Rodney and laughs at him behind Sheppard's back. McKay looks defeated.)
