The weight of what she's trying to do keeps trying to settle in her gut, so she's running, less because the question is so urgent that a minute matters and more because she feels like if she could just run fast enough, the weight couldn't catch up to her, and would be left trailing behind her until after the decision had been made, at which point it couldn't dissuade her from going through with it anymore. She's tired from the cut across the desert, and she feels sick about everything they've learned about the fact that Thuvia has attacked them, unprovoked, with no justification other than their stomachs, and she shouldn't have to deal with this problem, not on top of everything else. But she does.

She doesn't actually even know where Elie is. Her first guess is the tent where she last saw Uncle Jacques (as her brain insistently labels him, nevermind that he's only an uncle to Catherine). 

"Is Elie in there?"
