Will comes back after Edward is in bed, he knows that his brother needs to rest. He walked out and sees her injured and he sighed "Really! come on take the medicine and at least make an effort to get better, if you leave it thats not even helping your self and I offered help." he didn't like when his help was turned down in situations like this.
"the medic won't be pleased if I call him and he sees that." 

Edward was laying in bed under all the covers, thinking of his dad he began crying, He was quite miserable, he had broken down now his brother was out of the room.
