Interesting, very interesting. I couldn't have predicted that it was through Lizzie's disappearance that we'd finally get a follow up with the Mallers. I would be interested to see if Scratch has changed somewhat since we last heard from her, and if she will take the act of good will by Pegs (Through Angel), into account.

Steven may be the mole, but somehow I'm not sure. I'm not certain if he was merely a plot device to cause a transistion of leadership between Burt and Michael, or if he has any further involvement down the line. He almost had too many lines in this episode to be a minor character...
