During the scene where Morgan was shot and laying on the Billiard table dying, Wyatt is hovering over him and touching his face with his blood soaked hands. But none of the blood is wiping onto Morgan's face.
Yup. I noticed this the first time I saw the movie. Wyatt has his entire hand on Morgan's head and is gently stroking his (Morgan's) forehead with his thumb. His hand is covered completely with blood including the underside of his thumb. But yet none of it rubs off onto Morgan's forehead.
Also, after Morgan dies, Wyatt runs outside into the street where it's raining quite heavily. His hands are covered completely on both sides with blood. And yet, when he brings them up to look at all of the blood on them, you can clearly see that the blood itself is not being effected in any way, shape, or form by the now pouring rain.
Who knows, maybe the director was trying to symbolize (at least for the audience) that blood was truly thicker than water (Yuk! Yuk!).
