Oooo Jesse is dead. Caroline is pissed. Bonnie has new hair. Crazy Dr Maxfield was pumped full of flesh-eating bacteria and rabies. Damon has his own story with being an Augustine vampire. Bonnie and Jeremy had sexytime in mood-lighting.
There is a new breed of vampires who feed on other vampires (Jesse is one of these hence why Elena staked him to keep him from eating Damon. Miz assumes this is because someone wants all the “old” vampires to die out?). Katherine tried to kill herself and Stefan saved her: Hey, you’re Katherine Pierce…suck it up.
