The Vampire Diaries Season 4 Episode 14
Down the Rabbit Hole
Katherine returned to The Vampire Diaries this week, knocking out Elena at the bottom of the magic well and then seemingly killing Jeremy in order to use his blood to feed and wake Silas and then grab The Cure for herself.
Follow all that? Good.
The evening's other big development was that Klaus allowed Tyler to get a head start, for Caroline's sake. He still wants to kill Tyler for turning on his Hybrids, but Tyler escaped town for now and we don't know where he ran off to.
