Paul Wesley and Kat Graham

The Vampire Diaries' Kat Graham says her character Bonnie isn't always the fan favorite — and she's more than OK with that.

"[They've] made Bonnie a character that people either worship or go against because she goes against the vampires," Graham told TVGuide.com on the Atlanta set.  "All you can really ask for is that you give people those reactions, evoke something. I don't care what it is as long as you feel it."

Is Esther for real? When is Tyler returning? Vampire Diaries burning questions answered

On Thursday's episode, Bonnie is in a particularly sticky situation. She and her estranged mother Abby (Persia White) are an important piece of the puzzle for Esther to carry out her plan to eviscerate the Original siblings. Bonnie is further torn when her best friend Elena (Nina Dobrev) has reservations about killing Elijah (Daniel Gillies).

"Bonnie's not a vengeful person, there's always a purpose behind [her actions]," Graham says. "Whether she's wrong or right by audience standards she firmly stands by it. If she goes against Elena, or even Elena going against Bonnie, it would be because they both have this conviction that what they're doing is right. That's important to remember watching the upcoming episodes."

With Abby on Bonnie's side, the two are not only exploring their strength as a mother-daughter witch team, but a possible relationship that they've never had. "Bonnie is making an effort and I think Abby is too ... to try and keep everyone in the town safe and to try and be there for each other. How successful they will both be is yet to be discovered or seen, but for right now the effort it being made," she says.

Graham adds that the Season 3 take-charge Bonnie has grown leaps and bounds since the girl in the pilot. "There's a courage now," Graham says. "In the beginning she wouldn't have gone against so many people because she was still figuring out who she was. By the second season she knew who she was and by the third season it's her doing something because of who she is and she has the power to do it." And as Bonnie continues to puts herself in the line of fire, Graham warns that it could lead to grave circumstances for her. "I love that they play with my mortality so much," she says. "But I don't think there's anyone you shouldn't be worried about."
