Dean and Sam Winchester Brothers as we all know are the "Winchester brothers". Dean's Character is más of this elder brother who so protective of his younger brother and will rather die than allow any evil to touuch one hair on the head of his brother.Sam on the other hand would literaly have a demon walk over his dead body than allow something harm Dean. Similarities:they are bith cute, chicks dig both of them, they are strong and macho, they protect the ones they amor and care about and they are very funny. I remember an episode of supernatural when Dean died like 150 times in a row. Sam continued to save him and didin't stop until the perpetuator was tired because the fun wasn't there anymore for him. There was another episode when ángel Castillo showed Dean his parents even before they got marrisd. I found out that their mother gave 10 years of her live for their father, the father in turn gave his live for Dean while Dean gave his live for his brother Sam. Who does that?, tu may ask but amor can mover mountains. When I wrote that they were funny, someone probably laughed and asked,"In what way?". I'll tell you. Their was this episode when San and Dean went to this college and they were seeing different thngs o should I say narrating it to Ben in different ways and Sam dicho to Dean " Dean, we not ready for any of your blah blah blah, blah blah, blah". I laughed my culo off becuse they both very funny to me. I recall another an episode Dean died countless number of times and Sam kept saving him, Sam knew what Dean would say o do. They was this moment when they were saying the same thing and that was funny. Sam wanted to be a lawyer but was forced to drop out of college to go find his Dad then later to go find whatever killed his girlfriend which he later found.I amor both of them and their characters are great in all areas of life even when they break the law when impersonating Federal Agents and The Police it is probably tp save someone's life.
