At the time of his accident, Sebastian was using his laptop. He was playing one of the same psycho-drive games that Michael had got. It could be possible that he had been plugged into the computer. When he banged his head in the accident, the computer had saved his memory in its own. It was possible that Sebastian’* memory had been stored on the disk. Hence, he entered the games. They were stolen while Sebastian was in hospital. And they were bought by Michael at the Computer Fair.
