"You got tuberculosis..." The maester says solemnly as he washes his hands. You had been coughing for a while now, longer than a normal cough would be, and when blood started to show, Rhaenyra forced you to go to the maester to get checked out
"What? It can't be tuberculosis!" Rhaenyra says, trying to deny the truth as you sit in silence. The news racking your brain, as in a few months or even weeks you would be dead...
"I'm really sorry for you, it's hell of a thing..." The maester adds as he sits back down in his chair. "The best thing is rest-" He goes to add more but Rhaenyra cuts him off "Do another test! It can't be tuberculosis!" She demands the doctor, the thought of losing you almost killing her "Princess, I'm sure it's tuberculosis. And as I was saying, the best thing is rest in a place warm and dry..." The maester continues now, his voice full of pity. "With yout stage of progression, I'd say you only have a couple of months left... I'm really sorry for you..."
Rhaenyra has tears in her eyes now as she looks at you, seeing how blank faced you are "My love? How are you so calm right now?!" She snaps, buts is clearly just the grief, not actual anger at you
