Yu's Shadow is, in essence, the embodiment of his repressed fears and the emotions tied to his failings within the Tower. His fear of losing those he lets close to his heart is nearly overwhelming... but coupled with it is his own helplessness in the face of the mod events where he's forced to either watch them die or suffer excruciating pain, unable to do a thing to help them. He fears isolation, being separated from his friends and loved ones....his family and the reasons he's managed to come so far.
He suppresses what he could be; the same person who can lose touch with reality and the truth that they sought for and taking another person's life. Disguises his fear of being alone and left behind because of his action or inaction with the calm facade he always wears. Because, in the end... what he has is "enough." Even if he's deluding himself in the process...
"You already know the answer, don't you?" "What-?" "I fell from the path I know I was supposed to take. I was afraid that if this continued, I'd lose my friends and have to go on alone. I don't want to be alone anymore... I've had my share of solitude! I wanted to stay with everyone... but I boarded that train and ended up here instead. I left them behind like I did the others, even though they were the only true friends I had. And now... they could all be dead, but I refuse to accept that reality. Even though I saw it with my own eyes." "No... that's-" "So what if it may just be an illusion. False realities they bestow upon us here are just as real. You know it, don't you? How easily it is for them to reprogram our minds, our bodies, our souls... We've seen plenty of that, haven't we? But that's fine... It doesn't have to be reality or illusion. I don't want to live a life without being connected to anyone! I don't care what happens to the world--no, the universe as long as I'm with everyone! But... who can accept a murderer like me, right? Isn't that why you still try to reach out to those assassins... me?" "No... that isn't-" "After all those people you saved, now you know what it's like to take it. You enjoyed writing that name down. You reveled in the sickening crunch as metal met skull. After all, they took away a friend... and cut them down with ease. You won..."
