I think Scout's mom would be the typical Senator's wife (Just like how Scout was like the typical Senator's son...)...Jake's dad--i hope he'd be someone nice and cool, I'm not sure what Jake meant when she said that she didn't have a dad- was he dead?/ did he leave?/has Jake met him at all?
As for Bella's dad, I think he'll just drop by every now and then, trying to be the father to Bella...but Charlie will still be more important, of course.
WB should never have cancelled YA. big BIG mistake...
