Eve thought about it for a while, neither of their chances were good but honestly she couldn't remember the lay out of the building and had no real idea of which way might be better. From what jay had said, up sounded better. "up-" she said as her breath caught. She gasped trying to catch her breath before coughing. Her throat was constricting, the dry air wasn't helping. She needed her inhaler, but it was gone. The people were supposed to give it back when they woke up but obviously that hadn't happened. 

She rest her head on the metal air duct, trying to take deep breaths between wheezing and coughing. This was the best she could do for now.
