Speculation about fight:
There are rumors that LS was kicked out of Sports b/c she was talking loud and bragging about taking Xanex and being drunk. I'm beginning to wonder if the reason for the fight at Smallwood may be because of that. It sure seems like perfect timing b/c it appears that the guys were waiting for them there. I am one to think that there are very few coincidences in life. The good ones are usually God moments, while the bad ones can often be explained if you think hard enough. Yes, sometimes we just downright have bad luck and are in the wrong place at the wrong time - but what are the odds that would happen to LS so many times in one night? (she loses her belongings, she leaves and her "friend" is punched in the face at the next location, she leaves and eventually dies or is abducted, which just happens to occur in a town with cameras ALL over and not one sees this event, and now she's missing). Those have REALLY big odds against any one of them happening to the same person, let alone all in one night. I just don't buy that they're all coincidental acts. Therefore, I think the way to solve this crime, is by determining which ones weren't coincidences.
I'm kinda thinking that those boys knew they were coming to Smallwood (at that time), since none of them appear to live there. They were waiting. If this fight had nothing to do with LS, why wouldn't they be waiting at 5 North? If they knew he was with LS, and waiting for them to come home, how would they have known they were coming back at that time? Surely, they weren't just loitering the halls, waiting for hours. Therefore, I'm wondering if they (or some of them) weren't in Sports. Perhaps they sold something to CR, who gave it to LS. Perhaps either they, or someone who called them, overheard her bragging. Heck, maybe she was even openly telling people where it came from. Maybe that's the reason they went after CR - to remind him of how "stupid" he was for giving pint-sized girls things that they shouldn't have.
I've even wondered if perhaps the fight started at Sports (inside or outside) or at least arguing, and CR/LS left quickly to get away, thinking that SW would be their quickest stop (not knowing that the boys would run there too). It could be that a group was waiting at SW and another near 5 North (alley).
