There's a 5th episode that's aired on ID that's really good that's kind of a "catch up" post-all this news breaking after the documentary started airing.
The sense I get from Drake Bell is that he more wanted those people to reach out to him specifically. It's great that Will Friedle talked about it on his Podcast but probably all of those people have not said anything to Drake himself, who was the actual victim in this ordeal. In the episode interview, Bell admits he's glad that Friedle made that realization and understood in some ways it was a hard thing to bring up in a work environment. The Variety write up makes it sound a lot more mean-spirited IMO.
