After two weeks of pondering many many thoughts (like most of you on here) I have some thoughts to share on this story:
I just read that Emmas mom brought FOOD for the SFWF participants and that knowledge brings me back to my original thought Dr. Kelley was researching this genre of people and music. This was why she took off think about it this could have been her BIG PROJECT of her career I dont know if any other big insider research projects have been conducted (professionally) on the Horrorcore scene, so this very well could have been her shining moment as a Criminal Justice professional. Dr. Kelly in the one photograph I see looks a little slipshod as if she has some emotional/mental issues as well which usually goes along with highly intelligent people (I know b/c most of my family have 150 + IQ and extremely high EQs and a lot of them have suffered from depression and the like). She may have been quite egocentric as well as her husband. If this is the case, I think her decision was not only imprudent, but quite Machiavellian. This explains why she would allow her daughter to attend this event and why she drove them (in fact I am betting she insisted that was the only way she could go).
I can understand why Pastor Neiderbrock covered up the facts about where he was going that weekend but it is still self-serving, certainly going against the altruistic values a pastor should uphold. I believe he was deeply afraid for his daughter but it may have come down to manipulation between father and mother (perhaps) the mother threatened to reveal some things about Mark that would be publicly embarrassing therefore the Debra gets her way, Emma gets her way and Mark is not humiliated publicly.
Emma gets there and I think the break-up was mutual. I have heard he was saying all sorts of cruel things to her and maybe she was like screw you I dont need this look at all the attention I am getting from all these other guys. And maybe he was getting heat from his ex-girlfriend about the little girl he was dating (I seriously think its a joke to call it that all facts considered). So Emma went off and partied with another group and Sam went solo or chilled with his ex-gf. Then they decided to be friends again and go back to VA or another scenario was Sam was about to snap and perhaps he got rejected by his ex at the show. Too much rejection and embarrassment perhaps he apologized to Emma about the asinine comments he made and she being a naïve 16-year-old blew it off and was just simply on a cloud from being with her family that she just brushed it under the rug and forgave him all is well right NOT SO MUCH!
They get back he sees the text from the guy she was with at the show and that just sent him over the top. I definitely think Sam was massively disturbed sociopath. He was living his fantasies through this music that the majority of these also disturbed people (sorry but thats my opinion) used as a form of artistic expression. This is not music IMO and they definitely need to think about how they are influencing these young kids seems to me these SKR folks were getting what they needed emotionally from these teenagers love, respect, admiration, trust, devotion, etc. they are using these confused kids to get what their confused and disturbed asses need.
