At first, when I saw the thumbnail on the search page, I didn't notice the chloroform pad and thought that Jessie was sweeping Alex off her feet with a passionate snog. ^_^; Surprise sleepytimes are just as much fun though. =^_^=
Well, obviously Jessica would feel threatened by Alex to start with, then there's Jessica's well-known penchant for stealing things, and Alex certainly has things to steal. Then of course there's a whole other world of nastiness in Jessica too. Who knows?
