Shane: Come on!
Confused Audience Members: Wait. Okay, so Stefan knows there's only one
bore cure for immortality aka vampirism buried with Silas, but he shouldn't know that Silas can't bring back the dead, or might be disinclined to do so. The story is that Silas first invented a cure for mortality. He took it, but Q killed his lovah, before he could give it to her. He's supposedly an all-powerful sorcerer who is going to raise everyone who died in service of raising him.
Recapper: Okay look, first of all, the Fellowship has no plans to resurrect Silas, and with Shane disabled, Stefan assumes that's going to be easier to avoid. Secondly, Shane's belief that Silas would restore all these lives is based on nothing but communication with Caitlyn's spirit -- which, thanks to Gimmick Grams, seems like it wasn't Caitlyn's spirit, but rather, it is Silas pretending to be Caitlyn's spirit. Stefan doesn't know that yet, but I figure I can credit Stefan (and would credit Damon, were he in Stefan's shoes) with figuring out that's a load of b.s. Lastly -- and this is the most important part -- it's not in the script, dears.
Confused Audience Members: Damn it. We are Rebekah and the writers are the Fellowship of the Falls.
Recapper: Me too, dears. Me too.
Just then Caitlyn, or Silas-As-Caitlyn appears before Shane. When he says he's sorry for having failed her, "Caitlyn" shushes him and says he did everything she asked him to do. Everything is going to be just fine. When she disappears we cut to...
Confused Audience Members: So wait, is that really Caitlyn's spirit?
Recapper: It beats me, but it doesn't matter, so hush.
Silas's Burial Chamber. Jeremy and Bonnie approach the corpse. In its hands is a small wooden chest.
Jeremy: How is that supposed to cure every vampire in the world?
Bonnie: I don't think it is.
Jeremy: It's stuck. Help me move it until something wicked this way comes.
Bonnie: OMG. He's been frozen like a vampire statue for 2,000 years. There's only way to unfreeze him. We have to feed him our blood to get the cure out of his hands. We have to wake him up.
Recapper: That is a spectacularly bad idea. Ever since Damon used his *ptui* sire bond to cure Elena of the blood bag aversion he undoubtedly caused, she's been doing better at being a vampire. And ever since you, Bonnie, showed Jeremy how to circumvent his natural impulse to kill vampires, he's kept it in check. Get the hell out of there, now. They don't listen. We cut to...
