The Vampire Diaries Season 4 will be all about Bonnie.

Sorry, excuse us, Katherine: We man Bon-Bon.

In the first Vampire Diaries clip from "Graduation" released by The CW, we saw this witch lying by omission to Caroline, mentioning a "snag" but not specifying that she's, you know, dead.

In our second sneak peek, we see Bonnie walking the halls in her graduation gown and approached by Katherine, who makes a request and also issues a threat. She doesn't seem remotely scared by her unexpected partner in supernatural crime. But should she be?
