I'm not sure if I like this, but I'll go with it for now.
Better not make Silver angry when he's working!!! JUST KIDDING he would only use that knife for cooking. Or at least I would hope.
He's a relatively minor character, so he probably won't show up too much. Silver is a very angry and frustrated android. He had a pretty rough life of servitude with his previous master and because of that has a lot of trouble being respectful to others. He has virtually no friends and basically fucked up every relationship he's ever been in. He also had a thing with Fernando for a couple years (a long, long time ago) and they were even engaged at one point, BUT HE MESSED THAT UP TOO. Hopefully someday he'll get his act together.
The only thing Silver doesn't suck at is cooking and owns a restaurant in Theta. It's pretty successful for the most part, but probably only because he doesn't interact with the customers often.
