Aww. Gale thinks they can both make it and Prim's been making lots of progress so he's not gonna wanna give her too much of a pep talk since he thinks she should find her own comfort in Peeta's plan. This should be good news for them, not bad news after all.

I doubt Katniss would mention her talk with Gale since she figures if he knew there were feelings floating around, Haymitch might get a bit mad because they can distract people. >__> She'll want to distract herself since Gale being in love with Prim is gonna be a lot to think about and why not think about the person she's in luff wit? What could possibly go wrong?
