Well, the bad news is that NBC is not ordering a full freshman season of Constantine. Word has it that there will just be the initial 13 episodes. But, apparently they have not actually decided the shows ultimate fate, with the powers that be reportedly not having quashed the idea of a second season for the series. So, if you like the series and want it to return, you should probably hit up Twitter and use #SaveConstantine in tweets to NBC and using the handle @NBCConstantine. It certainly couldn't hurt!
Meanwhile, the freshman season is rolling right along so enjoy it while you can - just in case! Here are the details on tonight's episode "Rage of Caliban" - when a young boy is taken over by a malevolent spirit, John must put aside his misgivings over exorcising a child and convince the parents that their boy is not all that he seems.
