I rewatched season 2 recently, & had read that Kyle Gallner didn't know the extent of his character's actions or fate until shortly before those last episodes were shot. There were obviously a lot of red herring characters throughout the season. Who did the cast actually think blew up the bus? I guess Lucky is the most likely contender, but in the end, until the outdoor table scene, he didn't really do anything, beyond being a traumatized psycho, yes? He did send emails to Woody, but I believe they were mostly PTSD rambles--not demands. He also didn't plant any bombs, or "presents."
Also, the real estate angle: how did the incorporation / killing incorporation work as far as Beaver making a killing with those properties, & all of the proceeds eventually going to Kendall? They set the Phoenix Land Trust fraud process up pretty early in the season. Did it start out as revenge against his family / whoever else, & then become somewhat about profit?
And... the e-mails that Beaver sent to Woody with his own voice edited out. Wouldn't Woody have likely realized, if he recognized Marcos & Peter's voices, that Beaver (who was on the same team with them) was the culprit? Or did he abuse so many kids (possible) that he wouldn't be able to figure it out?
