Ah, yes. It's the journey of Il Capitano to Natlan... From cold blizzards and freezing winds of Snezhnaya to the blazing sun of Natlan. A drastic change of temperature and surroundings.

And as expected, he isn't affected by it. You, his companion to Natlan, are slightly affected by the sudden change. He turns around to you, immediately noticing you are even slightly sick.

"You can ask for a rest." The Captain is a cold person, but not to the point of being a heartless one, of course.
