Given the fact that Inuyasha brought up how he was sweating, it made it impossible to tell what had occurred next.
Said hanyou was able to tell though because of the fact he was laying next to him and watching him so closely.
Apparently, Sesshomaru was dreaming about a past memory that brought him a great deal of sadness because a tear trickled sideways out of the corner of his right eye.
Sesshomaru coughed a few times and tiredly looked at Inuyasha.
He gave him a weak smile because it was clear that he had all the strength beaten out of him, due to suffering from numerous fevers for several days.
Thanks to his fever taking a spike from the coughing, he was left panting hard in his father's arms.
Considering the medicine was only just beginning to work, Sesshomaru was basically left in the crossfire.
