Sansa's hand closes on Luna's and she gives it a little squeeze, as much comfort as she can find a way to give. "There's nothing we can do back there," she says quietly, meeting Luna's eyes. "We wouldn't get anything, and we wouldn't help anybody. We'd only die as well, and then our District would have lost half its chance at winning." From her tone, it's clear she's had the same thought about going back - it's just that in her case, she analysed those thoughts back in the safety of the Capitol, a week or more ago. Still, she looks pale, and avoids looking in the direction of the Cornucopia.
