Why would Belle have something to do with putting him there?
Rachel knows her well and recommended he talk to her right away when he had the chance to help him and his team etc I have no reason to doubt Rachel because of how well she has taken care of them not to mention how much Rachel trusted him to talk about Talia that was a big step for her.
Belle apologized like hell to him stating she should have handled them sooner so that shit wouldn't have happened.
Further more that big dude could have tore MC's shooting arm up but he didn't he went for the opposite side he worked for Belle or still does and had to play the part to not bring attention on to himself other wise why would he have held back on MC.
There's a lot of little things if you go back through slowly and pay attention my only thing is why the hell was Charles high af on something and Ryker as well? I found it odd they were both on something but no one knew what?
So that begs the question did someone spike their drinks or did they take it them selves knowingly?
Also why was Ryker hell bent on finding Charles and willing to kill or kidnap anyone who got in his way?
We knew Belle was going to deal with them after the talk she had with MC at the event but something happened before she could do anything from what I could see.
I dunno I am about to get a new pc soon and I'm probably going to do another playthrough a fresh one with no saves or anything so I can see what else I might have missed.
Ok don't forget Rachael and Belle had a falling out, so while she vouches for her they have not been friendly in a while. How long we don't really know as well as we don't know why. I trust Racheal not Belle (Yet).
Sorry but if I set someone up and don't want them to know I am going to play the nice guy role too. So sorry I am the most important person at the school, but never talked to you until the night you get the shit kicked out of you. What my inside guy was there too oh my bad I thought he was telling me what Ryker was up to but he mysteriously went dark a few days ago. How convenient, come on tell me that is not odd.
As for Ryker and Charles I never once trusted them at all. I knew something was up with those idiots from the first time I met them. As for someone spiking them I am sure it is possible or they both took the same drugs knowingly. Don't forget Charles was acting funny earlier in the day too.
Pretty sure Ryker found out Charles lost his job and thought the MC had something to do with it which is why he was looking for Charles.
We can assume Belle was going to do something but she also could have said that to get the MC on her side.
I am not trying to discredit what you are saying but you can make a case that Belle is the mastermind behind everything or that what she says is true. Only time will tell, and right now I can't fully trust her yet. Trust needs to be earned not handed out freely.
