I wasn't watching back when Ryan was on his original killing spree. Did he always do it with such "flair"? I mean, Mary Pat's head in the apple-bobbing barrel was deliciously evil/scary (on Halloween), and "the rest of her" at Ava's gallery was a twist I did not see coming. Anyone can just go around bumping people off, but setting up those freaky situations takes a Special Level of Crazy. I guess framing Carly for the crime was the best course of action, since everyone knew how much she hated Mary Pat (and Ava, the recipient of the "rest of her"), and if Carly's busy trying to prove she isn't a killer, she won't be snooping around Ferncliff.
The main thing bothering me at the moment, though, is whether Ryan's interest in Ava is that of someone looking for a new obsession, or that of someone seeing a kindred spirit, or perhaps just someone he could frame for his crimes later on. He certainly wants to know more.
I'm not one to give the writers much credit, but they really did deliver when they were tasked with creating a "really good story to bring back Genie Francis". It might be Lindstrom's storyline, but she's getting really good stuff to play and doing what I like to see her do.
