The idea of leaving her home she had made here in the airport wasn't something she really wanted to think about. But, she knew that he was right. If they wanted to survive, they had to get moving. She frowned slightly, especially at the comment that the aliens might be wanting to take over the world. The fact that they might really be trying to get rid of the remaining humans, if she and this boy weren't the last of the humans, was scary to her. She hadn't seen an alien since she was seven years old. She knew nothing about them. She didn't know what they could do to stop them. She didn't even know if there was something they could do to stop them. For all she knew, there was no hope for the human race. 

She looked down and thought about what he had said for a moment, biting the inside of her cheek as she thought, before she finally took a deep breath and nodded, "We do need to get moving. If they are this close, then we are in danger." Standing up, she went to grab her backpack, going through some of her things. She grabbed a change of clothes, a few hygienic products, and mainly food that they could take on their trip. And, after that was all packed, she went through her clothe again, picking out the warmest clothing she could find, figuring when he said they were heading north, they were heading for the colder weather. She pulled out a sweater, jacket, and boots, throwing them on rather quickly, reminding herself to loot a store of gloves, a scarf, and maybe a hat later on the run to keep herself warmer. 

Once she had all this done, she threw her back pack onto her back, looking back to him, placing her pistol at her hip, "Let's head out before those alien get any closer. I would really not be on the receiving ends of those guns you talked about."
