Sam is usually kind, empathetic, intelligent and independent. In the 200th episode, he is described as 'sweet, brave, selfless Sam'. He is often the exasperated voice of reason in his relationship with Dean, who in turn sees him as a geek or prude, and teasingly calls him "bitch," to which Sam usually responds with "jerk". Sam is usually assigned the role of researching information for hunts; he is the "brain", whilst Dean is the "muscle". He normally remembers details that Dean overlooks.
