How long can Bonnie keep her death a secret?

On the Vampire Diaries season premiere, summer is over which means Bonnie (Kat Graham) will have to find a new excuse for not being back from traveling. But the former witch can't bear to tell her friends the sad news about her demise, which means she — and Jeremy (Steven McQueen) — plan to keep up the ruse. But will it be long before even Jeremy is tired of telling the lie?

In our exclusive clip from Thursday's episode (8/7c, The CW), titled "I Know What You Did Last Summer," Bonnie explains to Jeremy why she won't give up the truth and why they're lucky to be in their current situation.

"How many people die and still get to talk to their best friends?" Bonnie says.

"How many best friends can't feel each other?" Jeremy responds.

"[Bonnie's death] creates this intense intimacy, even as a friend, that they never had before," Graham recently told us. "There were always distractions and they weren't ever forced to always just 'be.' You'll see a lot of us working together early on in the season."
