Yeah. They also gave Nikolas some mysterious disease that causes "rage blackouts" of a sort. And they put him in the room alone with her just before (and after) she died. But he doesn't remember anything except finding her body. There are other suspects, of course, but he's all guilty thinking he's her killer. Also, he's having hallucinations of Emily still hanging around and talking to him like everything's normal--except that he's the only one who sees her. (Blah)
Speaking of killing off characters that don't warrant the axe, I've heard about a dozen spoilers that they're going to kill Georgie, too, because Lindze Letherman's contract is up. Instead of killing Maxie (if one character ever deserved it...), they're probably going to kill Georgie as an excuse to get Felicia back for the funeral. And they're using her death to further the "Port Charles Strangler" arc right after the Halloween/Black and White Ball arc that went on until Thanksgiving. It's too much right after that.
