The fact that he was so obsessed with the idea of returning to his childhood mindset and home, that he risked, and lost, everything... his place in the world, his place in time, his body, the privacy of his mind... to try and return to that happier time.
That he made a tragic mistake (he was too excited by the idea of escape and exploration and didn't read the fucking manual) and was trapped, aeons before his own time, in a body that wasn't his own, competing with its native consciousness, and still managed to endure those long centuries and eventually make his way back to his native Earth.
