Molly was working with the Vampire Authority and created the iStake -- a wonderful contraption that didn't work. They have her time to fix her mistake and Bill later uses it on her when she refuses to worship Lilith.
Was there anyone who didn't jump up and applaud the end of Maryann's reign? Shapeshifting Sam joined her celebration in the form of a bull and took her out. Yay!
Bill's maker tried to steal him from Sookie and was damn near able. In the end? Sookie tells her "I'm the bitch that's gonna kill you" and a minute later her dream came true. Gooey.
An old faerie restrained a thousands years old vampire with a big vendetta against the Stackhouse family so Jason could stake him before he took Sookie. Go figure.
Sookie and Jason were left very alone when Arlenes' boyfriend Rene turned out to be a serial killer named Drew Marshall and Gran was one of his victims.
