But there is no other side. I know this before anyone else, even though I am furthest from the top. My eyes catch on a funny, rippling square hanging like a warped pane of glass in the air. At first I think it’s the glare from the sun or the heat shimmering up off the ground. But it’s fixed in space, not shifting when I move. And that’s when I connect the square with Wiress and Beetee in the Training Center and realize what lies before us. My warning cry is just reaching my lips when Peeta’s knife swings out to slash away some vines.
