Okay, I have to indulge in an aside here: It seems a LOT of people took this speech to mean that Shelby is Drew Thompson. I admit it could possibly make sense from a dramatic standpoint, but I think there are MANY logistical issues that make that theory problematic; in other words, if it does turn out Shelby is Thompson, I'm likely going to be writing a paragraph or two on why I think it doesn't make sense. I do think Shelby might have been close to Thompson and have an agenda in the investigation, but that's not the same thing at all. Still, if it turns out to be the case, maybe the show will change my mind on the feasibility of his conduct up until now.
In any case, we have more pressing issues to deal with, as Ellen May guesses that her first step in becoming respectable would be "to get right with the Lord," and Shelby gets REALLY close to drawing a confession out of her -- but he gets a phone call we'll see he needs to deal with.
