"Yeah... I was kinda just thinking about that. There's... a lot of houses here, with no real reason why they should be?" she pauses, her head getting a bit ahead of her, "They shouldn't have had this many empty houses ready unless they knew they'd need them. But they didn't know we were coming."

So it doesn't add up. What would they need so many people here for???

Unfortunately this does mean she's getting a bit off-topic, even coming to a halt as she pauses, eyes staring off unfocused as she tries to puzzle out possibilities.
