You Kill Me (In a Good Way) (Hunger Games/Supernatural)

"Sam Winchester!" A woman with strange pink hair cried. My mouth dropped open, my eyes widening as my heart pounded. Sammy. No. Not Sammy. I knew how this worked, knew how these games worked. I couldn't let Sammy go out there, not then. He was strong, sure, but strong enough to win? Not hardly. I couldn't risk it. I'd been to the pit and back already, and I refused to let my brother risk going there. I was important to Cas. If... If he could bring me back once, he could do it again.
