Kellen, I don't know why he needs attention. Maybe it has something to do with height, standing as middle child, or some bizarre effect of drinking water in Utah. I have heard that he has had some run-ins with skin walkers, I can only imagine that those type of experiences would cause some kind of trauma. I guess in Kellen's case it must have caused some kind of attention need to cover up the scaring of meeting a skin walker, or something like that.
