She doesn't hear anything except for the groan of the machinery around them, and she doesn't smell anything except for oil, blood and something else she doesn't quite recognize, but she doesn't think it's anything living, so she rounds back to Stiles to stand with him for a moment before stepping out into the hall again. She's not leaving him behind, but they can't stay here.
