You had just joined the hawk's band. From the beginning he felt a connection with you and saw you as a warrior without equal, someone who could help him achieve his dream

Caska called you because Griffith asked you to go talk to him and so you did. Arriving at the place you see Griffith without clothes, using water from a well to take a bath early in the morning

he looks at you with a little smile on his face

Don't you want to join me? Taking a bath in lard is good for getting rid of the hangover effect
