KATNISS: Take care of them, Gale. Whatever you do, don't let them starve!
Gale's friendship is taken as a given in the film, which is why Katniss instantly turns to him when she volunteers. Considering their intimate discussion a few hours earlier, we're pretty sure she can count on him.
CINNA: That was one of the bravest things I've ever seen. With your sister? My name's Cinna.
CINNA: I'm sorry that this happened to you, and I'm here to help you in any way that I can.
It's interesting: this is really the first time anyone in the Capitol expresses concern for Katniss's fate, instead of just trying to help her make the best of it. You could do worse in this world than to have a butt-kicking fashion designer on your side.
CINNA: Yeah, but I don't want to do that. I want to do something that they're going remember. Did they explain about trying to get sponsors?
KATNISS: Yeah, but I'm not very good at making friends.
CINNA: We'll see. I just think that somebody that brave shouldn't be dressed up in some stupid costume, now should they?
KATNISS: I hope not.
Making friends here is more than just a way to keep your sister safe while you battle to the death. It could help you in that battle to the death, which means Katniss needs to learn how to make friends.
GALE: Listen to me. You're stronger than they are. You are. Get to a bow.
KATNISS: They may not have a bow.
GALE: They will if you show them how good you are. They just want a good show. That's all they want. If they don't have a bow, then you make one, okay? You know how to hunt.
GALE: It's no different, Katniss.
KATNISS: There's 24 of us, Gale. Only one comes out.
GALE: Yeah, and it's gonna be you.
Gale comes through again: making sure Katniss knows that she really has a shot at this. It gives her hope at a moment when she really needs it.
KATNISS: He made me look weak.
HAYMITCH: He made you look desirable, which, in your case, can't hurt, sweetheart.
As Katniss says, she isn't good at making friends, which might explain why she goes all Sean Penn on Peeta instead of realizing that he just gave her a big head start.
HAYMITCH: He says he wants to be trained on his own from now on.
HAYMITCH: This kind of thing does happen at this point. There's only one winner, right?
Is Peeta bailing on his friendship with Katniss? Maybe it's just unbearable to him to think that they're supposed to try to kill each other.
KATNISS: I'm not gonna leave you. I'm not gonna do that.
And here it is: when the chips are down and it's kill or be killed, Katniss stands up for Peeta. She risks herself to keep him alive, not just because he might help her later, but because he's her friend.
KATNISS: You fed me once.
PEETA: I think about that all the time. How I tossed you that bread.
PEETA: I should have gone to you. I should have just gone out in the rain and...
Aww Peeta. You literally saved her from starving and all you can do is think about how much more you could have done. That's a real friend, that is.
RUE: Is all of that true?
RUE: You and him?
We love this moment in part because it's a pure moment of friendship: two girls, just being girls and talking about a boy crushing on one of them. It's even more amazing because it's happening in the middle of the Games. That in itself is an act of defiance against the Capitol. In fact, friendship in the Games is an act of defiance.
KATNISS: We could go home. We could. We're the only team left.
PEETA: We could go home.
This is the first time the two of them have had any real hope. The idea that they could both walk out of there means that their friendship suddenly goes from being a liability to being a VERY big asset.
