|“||Wait, wait! Mom! It's me! It's Caroline! Just come outside. I want to talk to you. I want to read your letter! Please. Mommy? Mom, please. Come back.||”|
The mother-daughter relationship between the vampire Caroline Forbes and the human Elizabeth Forbes was strained when the series began and after Caroline had become a vampire, Elizabeth was horror-filled at what her daughter had become. However, Elizabeth soon accepted her daughter and their relationship has become much stronger since then. Elizabeth is the person who Caroline loves the most.
In Caroline's early childhood, Liz taught her how to ride a bike. Originally scared to have her mother let go, Caroline begged her to hold onto her and not let her go. Liz assured her daughter that she wouldn't let go until Caroline was ready. Believing her daughter was ready, Liz let go. Caroline did well for a while before she fell and scraped her knee. Liz told her to never give up and to always get back on the bike, as there was nothing to be afraid of.
Years later when Caroline was in High School, their relationship became strained, as Caroline had thought that her mother cared more about her job than about her.

In Kill or Be Killed, A few days later Elizabeth Forbes is getting ready for another of the towns many functions, this time The Mystic Falls Historical Society Volunteer Day which Caroline signed her up for but believed she find an excuse to be off. However, Elizabeth is enthusiastic about the prospect of sharing the entire day her daughter. Caroline is folded arms skeptical.
Elizabeth ask her to give her a chance. Caroline warns her she is "in a mood" and it shows. "Goody for me" her mother says self-deprecatingly. She notes that Elena was there the previous night. Reflexively Caroline corrects her saying that Elena wasn't there but then she catches herself saying that Elena was there and needed to talk. She had realized her mother was unknowingly referring to Katherine Pierce.
Speaking of Elena she tells her mother that she and Stefan are going through a rough patch. Her mother asks if everything is going okay with her (meaning Caroline). Caroline says she is fine but Elizabeth notes that she seemed different somehow. Caroline protests that she is fine but Elizabeth comes back saying that while Caroline thinks that her mother doesn't notice things like that, she does. Defensively, Caroline says "You know, there's pretending to be mother and then there's reality. Let's not push our luck okay?" and she storms away.
Later Caroline and Elena are talking when Caroline sees her mother on a cell phone leaving the park grounds. Perhaps using a bit of superspeed Caroline catches up to Elizabeth, asking her what is wrong. She says nothing as she hangs up and closes the cellphone. Elizabeth says it is work, meaning police business.
Eventually they come across the cellar of the old slave quarters on the old Lockwood plantation. Caroline listens and hears her own mother say "He's not going to tell us anything. Kill them both!". Caroline is afraid to stop it because her mother will find out about her. Elena, disgusted, ignores her and runs down the stairway leaving a torn Caroline. She eventually runs down the stairs after Elena who had just hit a sheriff deputy with an old plank attempting to stop the killing. The deputy who was hit holds her at gun point, but Caroline, using her superspeed, slams shut a cellar door. Elizabeth asks Elena who else is with her. Around them Caroline uses her superspeed, frightening the cop holding Elena. Caroline runs behind Elena, comes around and defects the gun spinning the terrified cop around, holds him with her powerful arms and starts to rip out his jugular vein with her fangs; her snarling mixing in with his cries in terror and pain as she drinks his blood. Then the report from the other deputy tells Caroline she is being fired upon. Her mother looks at her with astonishment as Caroline walks out of the shadows breathing heavily. Then she stops and collects herself and suppresses her game face and she returns to human likeness. "Hi mom." she says to a shocked Elizabeth. Later Caroline is sitting on the steps of the cellar; her mother refusing to even look her way.
That night Caroline comes home to the Salvatore residence with a small travel bag of her moms clothes apologizing to Elena for being late that she didn't know how long her mom was staying over Elena tells her that vervain takes about three days or sooner to leave the body. Stefan joins them and Caroline ask if he got some blood in him and he tells her he feels much better. They reach the door way of the cellar the brothers are keeping Elizabeth in. She was just about to enter when she heard her mother say "Keep Caroline away from me please; I don't want to see her. Damon, knowing that Caroline was leaning against the door jam says "she's your daughter Liz." "Not anymore" Elizabeth says disowning her daughter. "My daughter's gone." "You have no idea how wrong you are about that!" says Damon and he looks at a hidden Caroline sympathetically.

Liz just ignores her, Caroline picks up her mother's tray and tells her she didn't care, just like before she was a vampire.
Minutes later they are in deep discussion about her lifestyle. She explains that she does drink human blood but it is from the stocks at the local hospital blood bank. It is not as good as fresh human blood directly from a living being but better than the animal blood Stefan tries to get her to drink. Elizabeth ask if she steals the blood but Caroline says Damon does, but she was pilfering his supplies. Her mother says she doesn't want this for her. Caroline responding with "...when life gives you lemons..." Then her super hearing picks up that Damon is home and tells her mother. Another look of fear plays on Elizabeth's face.

Liz arrived and shot at Damon but he moved out of the way and her bullet hit Jeremy instead. He was killed by her and since she was human, his ring wouldn't save him. Caroline, Bonnie and Alaric arrived to find Liz crying over Jeremy's body. Caroline tried to revive him with her blood but it was too late. Bonnie and Alaric then took him to the old mansion where he was resurrected by the dead witches. When informed of this, Caroline and Liz were reassured.
Caroline then told Liz, who was still a bit confused over the magic of everything, that she had once explained everything to her but that she had made her forget because she was scared about what she might do. She says however that it isn't something that she's going to do again as she doesn't want to be afraid anymore. She also says that despite her being a vampire, she was still her daughter.
