Madoka is definitely having a 'huh, wait' moment over here herself. It's so visible in her eyes as she looks over at Tidus, like she isn't sure where his confusion comes from. Sure, it's weird to have been stuck on the moon, it's not like that happens to just anyone-- but Tidus seems so nice and sociable, she figured he would have heard about that from Della by now if he talks to her a lot!

"She didn't tell you about it?" Madoka tilts her head a little, trying to think. Della didn't make it sound like a secret, so it's.. probably not bad for her to talk about it, right..? "I-- I'm not sure when it was? She said she was testing out some rocket and crashed on the moon and was stuck there for ten years.. But-- But she got off there again after that!"

Of course she has to quickly add that last part. She wouldn't want to make Tidus too worried!
