Lux considered the option of laying down and thought it was at least worth a try and said "Ok, I'll try lying down" so she dropped down onto her back and looked up at Maggie as they walked. she wanted to ask more questions but she knew she shouldn't talk while they were walking around, as people weren't supposed to know she was there, she still didn't quite understand that, she just knew it made her sad. but she knew Yato had told Maggie to take care of her and she trusted Yato so of course she trusted Maggie, so she stayed quiet as they walked, even though laying down was only marginally more comfortable then sitting up.
