Ooh Grace Manning! I wonder if there will finally be some Duncan and/or Faith? Not that I'm a big Duncan fan, but he was a big part of Veronica's life. Also excited about Weevil; there wasn't enough of him in The Thousand Dollar Tan Line.
Digging the way VM canon also allows for Veronica to question past decisions and actions (or inaction, as with Grace as a child). That girl's got integrity.
