I know that I've said this before in relation to "The Vampire Diaries" -- and it's going to sound extremely cliche, but I just need to say it one more time -- OH MY GOD.
Holy make out, Batman! After three seasons of major sexual tension, Damon and Elena finally gave into temptation and had a full-on make out in a hotel. Ironically, this was all Stefan's idea.
Stefan and Elena spent most of the episode together, much to the delight of Stelena fans everywhere. Sure, Elena was mostly just following Stefan around like a lost puppy, but it's not like she had any other choice.
