Shane may have been a douche,but he was a realist. He knew what they were up against and had what it took to survive.he just got a little to pushy for his own good,but he was a good asset to the group
Rick is turning into the same thing now, but he's a sissy at times. I would have shot Otis too like Shane did if they were both going to die anyways. Being a realist in crisissituations is important. What a great show. I love Grimm too though it's different.
