That would be quick if Mac and Christine got married within the time jump. We'll see. And also the finale talked about Adam being a CSI. Maybe he is now.
When I first heard about that I just thought, "We don't need another!". But if Danny and Lindsay decide to shuffle over to Montana then it could be really interesting. The last time we saw Adam with a gun (and only time if I'm not mistaken ) was way back in season 6.
