It takes her a long time to try and understand him, obviously. My problem is that I feel like her relationship with Natsuhiko won't be told well considering the remaining amount of episodes. She goes on with needing to protect him, yes, but did she ever act really fidgety or blush often? I don't think so. I hope they only put in Motohisa and Nagisa, I don't want to see Yahiro in the anime it would spoil LE to some of my friends who aren't finished yet _ I could also see them simply land to get information about Mikoto's whereabouts, maybe through Ron who I assume makes his escape now, since Masamune knows he was responsible for the explosion. To do that they will have to land and be stationed in a town, maybe Masamune meets Nagisa there. My guess is that they are ordered to fight against the army of Yuiga Shiro, which is how Kakeru learns that he is involved (since he said so in the preview).
