With the crash she turns around, she'd been inspecting the woodwork and not really paying attention to what Mondo was saying or the ziplock bag apocalypse. And that's how things are for Ryoko, if she's not looking at it, it's like she has no idea it happened or how it happened.

So when she sees it, she's surprised, not really concerned for Mondo because they're just plastic bags, they're not dangerous, it's just...wow, that's a lot of bags.

“Um...are you okay? Did you slip?”

Part of her wants to ask why he needs so many bags since with all the excitement she's forgotten why they're here, but she's not sure if that would be rude or not. So instead of that, she thinks a better question might be...

“Do you need help with those?”
