I've just got to say I love this show on so many levels! The latest ep, "Mars vs Mars" was a perfect example of what tv should be like.
Now onto the mysteries. I think that Lynn is really dead and someone might have just stolen her credit cards. I mean, no one around, convertible, obvious purse in car. It's the perfect scenario for a thief. So yeah.
As for Duncan. I've just got to say that I love him. He has so many layers that are slowly unraveling, making him all the more interesting. Do I think Koontz and Duncan (and probably the entire Kane family then) having the same doctor is a coincidence? No way. There is totally more to that and I can't wait to see it.
But I don't think that Duncan killed Lilly. They're making him way too obvious of a suspect. What I think is possible, like I said on ff, is that Jake or Celeste THINKS he accidentally killed Lilly in one of his epileptic (sp?) fits and is trying to cover it up. But I really don't think that he did it. The killer will most likely be leaving the show and Duncan plays way too an integral part in Veronica's life (past and present) to leave the show. So no way did he kill Lilly.
