She doesn't know either. But she has no other name to call him. In the other set of memories, in the ones belonging to Katniss Everdeen, she's never met this boy. She doesn't have a brother. Only a dead sister, to go along with a dead father and a mother who'll never be what she needs from her. Not that Katniss needs anything from anyone.

Katniss Everdeen is a girl who's best off on her own.

But Kitty? Kitty walks over to Jake and wraps her arms around him, never letting go of the archery equipment but hugging her brother just as tight. She's going to fail him. She already knows that. It's something Katniss is used to.

"I don't know."
