Yes, the heart was DNA tested and it was her heart.
I know she was supposed to be Goren's Moriarty, but Moriarty only shows up twice in the Sherlock Holmes stories. I think a super-villain is hard to maintain if you're not in comic-book land. (I say that as a person who is very fond of comic-book land.) Even then, Moriarty was supposed to be the mastermind of a great criminal enterprise, not a sociopath who largely worked alone.
eta: It also used the Ross-Rogers affair that's been hinted at all season. It was a continuity-gasm of massive proportions.
Was it a season finale? (I'm usually more aware of these things, but I haven't been paying proper attention to the L&O franchise lately. I think I'm suffering from L&O fatigue.)
It was really creepy AND loose-ends tying up. Does Goren really not know where his nephew is? (That would be the only loose end left.)
I watched it this morning and what a creepy way to start out a day.
Oh, and the Bones season premiere showed up in my tivo to do list!
I'm pretty sure Goren doesn't know where his nephew is. Donnie's mother said she hadn't see him for a year. I think he's been missing since he broke out of jail.
That must have been Warren Leight's last episode as writer and showrunner, before he left to produce
In Treatment.
He pretty much cleaned the slate for the new guy.
well, there is Luther Mahoney. Although maybe I liked that storyline because the actor was so good.
