you were laying there. coughing, sneezing, and sniffling. on the occasion, the coughs were getting so bad you began throwing up the food given to you by sanji. and then, you threw up blood. chopper had inspected you, and gave the unfortunate news.
you would not make it.
zoro doesn't get it. he couldn't. he doesn't want to understand. why you? is this some sort of twisted, cruel, and sick fate caused by the universe? the world was taking his only family left. his younger sibling. he can't stand it.
he can't believe it.
you were sick with an unknown disease, so it was basically incurable.
the crew left you and him in your quarters alone to let you both grieve. they understood the e privacy you would need. your final moments with your family is important.
zoro could only stare helplessly at your sick, pale form on the bed. a cold, wet cloth on your forehead to decrease the warmth in your body. the blankets kicked off at your feet. why was life so unfair? first kuina, and now you. death comes naturally, he knows that. but, he hadn't become the greatest swordsman yet. he hadn't defeated mihawk yet. he wanted you to watch him achieve his and kuina's dream like you had promised. to be by his side and achieve your own dream.
