Rake has a whispery voice and doesn't talk much after his brother was taken by the SCP foundation.  His real name is in a language no one can understand, only Rake learned how to speak english his brother didn't.  He goes out at night to go and try to find his brother with no luck, just like his brother he hates being looked at but pictures didn't disturb Rake as must as they did his brother which is why he hasn't been caught yet.
