All Renji could picture were the last fragments of dim memories he had of his father. He bit his lip and forced these into the back of his mind, because this was completely and utterly unprofessional behavior, to let his emotions take him over.
He did take the offer to sit, feeling his legs weakened, and extended a hand to study each of the medecine bottles, taking notes of their compositions, penning them all down.

Ssauke, meanwhile, had climbed on the bed to hug his brother. "You know, niisan, if we need money, I'm sure I can help out at shops after school!"
Renji gave a light smile at that, continuing his collection of notes. That boy made him wish he had a little brother of his own...

"When have you last been given an IV drip, or had any change in prescribed medecine?" he inquired, turning to another page of the small notebook he had brought.
