As originally portrayed by Nicki Aycox, Meg was tolerable. While it's hard to like anyone who sows dissent between Sam and Dean, Original Meg at least made things interesting. New Meg, played by Rachel Miner, only made things irritating. Not only was she responsible for the deaths of Ellen and Jo, but she's a huge flip-flopper! Is she working for or against the Winchesters? Who can even keep up anymore! Hopefully, we won't have to, as long as Crowley gets his way.
