Grace's Motive

Paul: Grace doesn't seem to have as much of a motive as other people we've talked about over the course of 20 odd episodes of this show. She's been consistent from the time she tells police what happened all the way through trial because she ends up testifying on her own behalf. But I'm also going to keep an open mind, especially once we get to the ballistics. Paul: Some people will kill in order to just kind of be able to move on. Is Grace one of those persons? Did she just decide I want to improve my life and Harry's done?
