Sol, always trained to have a simple mind, never thought about this before... His appearance was not looking very trustable to others, he knew that much, and understood doc now. He could be a spy, and he could mean to hurt doc. He stood and wondered for a second... There was no way he could prove that he is not a spy or something like that.
Sol got up, took his cardamine breather into his hands, and tore it apart.
"Doc... there is no way I can show you a proof about this," staring at the pieces of the breather in his hands, "but I decided to die instead of going back to killing innocents to live..."
Looking into the eyes of Doc from behind his strange looking goggles, "I am willing to let you test your unproven methods on me, but I am not dying as a slave to cardamine," his voice was calm while saying that...
Here I am now... my life depends on another person again... Sol thought, wishing it would be the last time either way, as a free man or dead.
