It was more than just having a light turned on after nearly thirty years in darkness- it was far far worse than that. It had taken years for Matt to give up hoping that his sight would ever be restored, even with all of his extra senses and abilities, there was at least a decade, from the time of his accident until his graduated from college, where he helped out hope that one day he'd wake up, open his eyes and would see. After all, God had performed greater miracles- making the blind see was old hat for Him by now, wasn't it? And hadn't Matt been faithful? Wasn't he doing good for others?
But his miraculous reward never came, despite the hardships and traumas that began to pile up. It was around then- when he'd lost his father and girlfriend all within a very short period of time- when Matt had stopped hoping for a miracle. He would never see again, except in the occasional dream.
So what Danny had done was far worse than simply showing him color. Somewhere, in the back of the darkness that had become Matt's world, Danny had lit a candle which had long ago been extinguished- a weak, feeble little light of hope.
It took him a long time for him to remember to reply when Danny spoke to him, and her gave his friend's arm around his shoulder a grateful pat as if to prove he was okay.
"People." He said quietly, not bothering to dwell on or discuss the emotions that this display was bringing up-- instead he was already moving on to the next thing, "I want to see my friends."
