So “Vampire Diaries” is back, and not a moment too soon. There are so many loose ends that need tying, what with that moonstone and ancient curses and dead werewolves and the like. Luckily, “VD” keeps things simple this time out, just in case you’ve been busy and had to reallocate the valuable brain space you once used for keeping your werewolves, witches and vampires straight for something like, oh, algebra or the intricacies of your data plan. But just in case you’ve forgotten, new girl in town/werewolf tried to kill Damon but bit Rose instead, vampire Caroline is torn between werewolf Tyler and nice boy Matt and Elena is generally a big, mopey bore. Caught up? Good! Let’s get to it.
