As I said earlier (rather inarticulately), both Dustin and Sean have been adamant that neither of them shared their experiences of abuse with any other team members, nor were they aware of any other team members knowing what they were going through, and as a result, both of them asked that all anger/vitriol be directed at the perpetrator of the heinous acts, Pete Werner. Focus should absolutely not be moved off of Werner, for any reason. On those points there can be no disagreement or casting of doubt.
In the last two days however, Dustin has now become aware, through Charles' own admission, that Pete drugged Dustin on at least one occasion. Aside from the ever-increasingly heinous nature of the abuses Dustin was forced to endure, it must now also be acknowledged that at the very least, the number of team members who knew what was going on is now non-zero. At least one other team member (Charles) not only suspected something was amiss, but was actually told outright by Werner. That certainly does not pass the stain onto every other team member, by any stretch of the imagination, but if even one person was aware, it can no longer be assumed that others didn't know.
I'm absolutely not suggesting that it is a fact that anyone else knew, but I have seen in other circumstances where individuals might know more than they are sharing, but because the core facts of the situation are already known and "out in the open", and because revealing that they also knew doesn't contribute anything to the known facts, they simply remain silent because admitting knowledge only reflects poorly on them (objectively or in their own perception). It wouldn't be the first time someone struggled with revealing what they know, only to feel relieved that what they know has already been revealed by someone else, and they can remain silent.

@JimmyV_2.0 , so sorry for the duplicative nature of the post.
