Cassie looked over at him when he started to talk about him studying up on medicine and such when this whole apocalypse started. Honestly that didn't seem like such a bad idea and didn't surprise her since he was carrying around that first aid kit of his in the bag with him. She thought about what he was saying and asking for a moment before she slowly shook her head, "No....its not stupid. Maybe far-fetched. But never stupid. I'll probably should have been studying up on that instead of the mechanics like my father did." Weaponry. Building. Anything that had to do with machinery. But then again, didn't medicine and machinery go together? Maybe, depending on who you asked. 

"If there is a cure, maybe we can find it. Once we get far enough north and find a place." I the aliens weren't following them still that is, "I can help. If anything I can help you....I don't know....build things? Set up a lab? I'll even attempt to assist you with anything else you need from me." She said, glancing at the road before looking back at him, the idea fo helping him find thi cure, if this was one, suddenly very appealing to her, "If you want me to help that is."
