I thought about the wedding storyline. If for some reason that Mac & Christine broke up before the start of S10 it would have been an interesting twist if the wedding was actually for Flack & Lovato. At least that's my though.
But it would have been that unexpected twist that would have had us all with our jaws to the ground. Is it odd that I am still having CSI: NY withdrawls? I can't even watch my boxsets. Good grief CBS what have you done to me....
