Yeah, the plane crash is a bit of a stretch. I guess he did kill the dude's daughter. That whole plot ark, with all the bear/eye in the pool foreshadowing and symbolism, seemed a bit unnecessary.
Obviously, the Jane and plane crash arcs were at one time going to be more important to the overall story, but for whatever reason they were abandoned.. Remember all of the foreshadowing on the scenes where the NTSB folks were investigating, and the two body bags were in the White's driveway. They showed this scene several times.
