Lin was debating whether she should run for someone. This boy- these other Tributes- hadn't been given a fair chance. Part of her wanted to scream to those watching, throw her head back and shout let's start over! This is against the rules! because none of them had even been touched. They all had a disadvantaged due to being infected from some outside source... right?

Her selfishness kept her from it. She realized starting over would mean losing her supplies, and half the Tributes already dead put her at a serious advantage. She's almost ready to feel relieved by this turn of events when she looks back at the boy she'd been trying to save... and realizes he's already dead, that he died right under her nose. It's not her first time she's looked upon a corpse, but Lin goes white. "Shit... Shit... Shit..."

The lawyer was once a decent person, and her desire to run away to avoid catching whatever virus this is is squashed under her respect for the dead. She bends down, claps her hands in a quick and silent prayer, and closes the boy's eyes. That should do it.

And before anyone can think her too kind or too soft, Lin steps over the body, stone-faced, and walks away as if the kill had been hers.
