That was 9 years ago before the first strange tingling that would herald the onset of his ALS. Now he lay immobile, remembering younger days when he could explore caves. He could barely breath on his own now. Passing days were spent fantasizing about being normal or, when he was more bored, of being something super human. Imagination was all he had to keep sanity and pass the days.
"It'd be nice to walk again wouldn't it?" A voice beside him asked. He couldn't see the owner of the voice. When asked later he wouldn't even clearly remember if it was a real voice or something he had imagined.
"Yes," he thought.
"Accept the exchange then?" He somehow understood the deal even thought it wasn't discussed. A chance for something more in exchange he would risk a horrible death but it was a death he could face standing. Anything was better than wasting away on his bed.
Guan never said yes... perhaps because he could not speak but he didn't imagine saying yes either. He had accepted the offer though. That much was clear, but much like other parts of the conversation he didn't quite remember how it had exactly went when he tried to recall events.
