While John was in town for the 150th anniversay party of Mystic Falls, he attended a Founder's Council meeting and warned everyone that there was a vampire problem. Blood banks were being drained, bodies were going missing. The official report that Vicki Donovan died from an overdose? That wasn't gonna fly, he said. Damon was also at this meeting and wondered what John's deal was. But Damon had another problem at home: Stefan was trying to ween himself off human blood on his own. Those two bags last week left him worried about what would happen if he continued down this path.
It was hinted, strongly, that Stefan has a history with human blood and what it does to him. But it was never revealed this week.
Elena was worried about her man, especially when everyone attended a Founder's Council party and Stefan was drunk. He said the alcohol helped suppress his cravings, but the dude wasn't himself. When a guy bumped into Elena on the dance floor and was a jerk about it, Stefan compelled him and almost made a scene. It soon got worse:
Matt's mother was a drunken mess, as she dealt with Vicki's death. Tyler was a drunken mess for the same reason. These two actually started making out at the party, a scene Matt saw and pounced on. He pulled Tyler away, and then Tyler went off. He beat Matt up pretty badly and then, when Alaric came to the rescue, we saw a glimpse of smoke (or something) emanate from Tyler's mouth. Another hint that he's a werewolf?
As we tried to digest this, John went up to Damon, outside the party, and introduced himself. He said he knew all about the tomb and even that Damon had opened it. Damon's reaction? He snapped John's neck and tossed him off the ledge -- but John then returned to the party minutes later! How? We soon found out: John has a ring just like Alaric's.
When Alaric and Damon pressed him about how, he let loose with a slew of information: he and Elena's father inherited the rings. John kept his, and gave his brother's ring to Isobel (!). He also told Isobel to find Damon when she expressed a desire to be turned into a vampire. This guy knows everything there is to know about Mystic Falls, including stuff about Katherine. Damon is fascinated, scared and confused.
Stefan shares a lot of those emotions because he came very close to killing the guy that was rude on the dance floor when he encountered him again in the parking lot. It didn't help that he got a taste of Mrs. Donovan's blood after he found her crying at the party, wounded from the aforementioned brawl. He then confessed to Elena that he'd never felt these kinds of urges before. Elena comforted him and viewers were left to think it was a breakthrough in his recovery...
... until the episode ended with Stefan drinking a glass of blood at home.
