Wish I dd, kinda, but I don't own NGE.
His eyes opened.
"... see color... again... retina... damaged..." Who was talking...? His senses slowly came back to him. The blanket he was under wasn't warm...
More importantly... where was Kaworu...? He... Shinji curled into himself, shivering. Remembering. What happened...
"... Thank you, doctor..." ...sounds like... Shinji slowly sat up. The room was white, white, white, and dull... The (white) door opened up and someone walked in, their head facing the ground. They...
"K-Kaworu...?" The person looked up. Yes, it was Kaworu. The teen smiled, and said, "Good morning Shinji. How're you...?" Kaworu sat on the bed close to him.
"Kawor--... Kaworu..." Shinji's eyes burned. He hardly noted Kaworu's skin was horribly pale and his eyes weren't the same lively crimson, and were.. a dark gray... Tears started falling down his cheeks.
"Oh, don't cry, my love..." muttered Kaworu, wiping away the saline water on his face. Shinji wrapped his arms around Kaworu's neck. He was warm, now.
"K-Kaworu, what h-happened? I thought you... Your arm... It was...!" Shinji hiccuped, and start sobbing into Kaworu's (once) new, and clean dress shirt. Kaworu pulled away enough to see Shinji's eyes, and that's when he noticed.
"K-Kaworu.. your eyes.. are... they aren't..." Kaworu's smile fell. "Shinji, the accident... your eyes were... The doctor said the... color receptors in your eyes were damaged, so... you can't... see color anymore..." Shinji stiffened in Kaworu's arms.
"W-What...? I can't... but... I..." Shinji broke down again, and clinged to his lover for dear life. "Kaworu..."
"It'll be okay, Shinji. Everything will be fine. Don't worry. At least nothing horribly bad happened, right?"
"Horribly bad? I can never see your eyes again, Kaworu! Never see the color! I can never... ever see you when..." Shinji giggled a little, then sighed. "Kaworu..."
"Go to sleep Shinji. You're probably still tired..."
"Just go to sleep..."
And his eyes closed.

Basically what happened was they were on a train ride, and the train sort of fell off the tracks, and rolled down a hill. Kaworu's arm was crushed by some of the debris, and Shinji... Shinji just sort of fainted after seeing Kaworu, and as he slept, some chemical seeped into his eyes, and made the rods and cones that picked up color in his eyes not work... Yeah, poor them...
