[Sadly, Yotsuba thought that she'd be able to accurately tell which was the wind was blowing if Alphonse wasn't holding her, so she'd had climbed up.]

Yotsuba's checking the wind, like you asked! It's fine! Yotsuba's good at climbing!

[Not that her face showed it was fine. Even with her coat and Alphonse's loincloth, she was freezing, and she wasn't smiling as she moved her arm about, still wincing every now and then due to the cold and the harsh winds. Eventually, she'd point her arm north.]

The wind's blowing that way! And Yotsuba's arm's red!
