"You're what he wants. It will work out, somehow."
- ―Esme to Bella
Esme Cullen (born Esme Anne Platt, previously Evenson, born 1895) is the matriarch of the Olympic coven. She is the wife of Carlisle Cullen and the adoptive mother of Alice, Emmett, Edward Cullen, Rosalie and Jasper Hale, Lucas Stone and Tiffany Stewart. Esme is also the adoptive mother-in-law of Bella Swan, Krystal Diamond and Jalen Long and the adoptive grandmother of Renesmee Cullen and Lucina Stewart and the adoptive grandmother-in-law of Jacob Black and Bryce Summers as well as the adoptive great grandmother of Evan and Sarah Black and Lucien Summers and the adoptive great grandmother-in-law of Luna and Korrina Snow and Damien Grant. She was previously married to Charles Evenson as a human.
In 1921, after losing her baby to lung fever, Esme attempted suicide, but her attempt was unsuccessful. Later, Carlisle transformed her into a vampire on her deathbed. Some time later, the pair fell in love and married, starting to build a family of like-minded vegetarian vampires around them. Esme possessed an unparalleled capacity for passionate love for those around her, which allowed the members of her adoptive family to consider her as the greatest maternal figure in their lives. She is the oldest Cullen in appearance by three years (though Jasper, Edward and Carlisle are older as they were transformed earlier in their lives). Her Life and Death counterpart is Earnest Cullen.
She is portrayed by Elizabeth Reaser.

A New Life

Esme meets Lucas.
"A human mother would've felt her heart melt from so much love."
- ―Esme on Lucas
Eight years later in A New Life, Esme meets Lucas Stone who was brought into his home by Renesmee after he was attacked by a grizzly bear for Carlisle to aid him. After hearing about how Lucas lost his family and has nowhere to go, the Cullens allows him to stay at their place. When Lucas went to bed, everyone including Jacob notice that Edward, Alice and Jasper weren't able to use their gifts on Lucas, everyone was uncertain if he's considered a threat but Carlisle decides that until they learn more about Lucas, they welcome him with open arms while Esme believes Lucas to be no threat. Her statement was correct after she spends time getting to know Lucas who thinks of her as another mother to him as everyone else got to know Lucas and all agreed that Lucas pose no threat and decided to allow him to become part of the family. The next day however while everyone was setting up a surprise welcome party for Lucas, Lucas was hit by a car after he pushed Renesmee out of harm and by the time she and Jacob hurriedly brought Lucas to Carlisle, he was reported 'dead' until Edward somehow heard Lucas's heartbeat but barely which made Jacob give permission to change Lucas. Three days later, Lucas wakes up from his transformation and joins the coven after being told about the world he lives in.
In the middle of August, Renesmee was missing. The Cullens were trying to figure out what happened to her until Lucas saw people, despite being invisible because Lucas saw their auras, attempting to kill the Cullens and warned Edward warning everyone else as they survived and caught May and Niall who are siblings and work with the Volturi revealing that Aro has Renesmee and ordered the two to destroyed the Cullens. The Cullens and Jacob arrived to Volterra to save Renesmee only to see that she's 'states' that she wanted to join the Volturi. However thanks to Lucas, he was able to rescue Renesmee seeing that she was hypnotized by May and Niall’s sister Olivia. However, Aro refused to let the Cullens walk away and soon everyone minus Lucas was restrained by the guards. Edward soon found out that the Volturi were the ones that caused the death of Lucas's family causing Lucas to go on a rage taking down every guard and member in his way until he reached Aro. Carlisle and Renesmee stopped Lucas just in time and Aro reluctantly allowed the Cullens and Jacob to leave until Lucas's rage came back causing him to mysteriously go unconscious when vampires couldn't.
After they returned to Forks, Lucas left the Cullens without giving any info since his aura blocks Edward and Alice's gifts except saying that he 'had to take care of something.' Fearing that he might be going back to the Volturi, everyone tried to convince Lucas to stay but he refused and left without another word. A week later, Lucas returned to Forks and explained that he went back to Lacey to see his friends before they go to college and visited his family's grave. Esme, as well as the rest of the family, allows Lucas into the family without the need for permission.
The Other Half & A Reason To Smile

Esme meets Krystal.
Esme hears that Lucas is in love with Krystal Diamond from school and she is very happy that Lucas is able to find his mate. Lucas and Krystal began dating after their first date where Lucas tells Krystal of the supernatural when she caught him hunting and Esme welcomes her into the family.

Weeks later, the Cullens were trying to deal with the disappearances of many residence in Seattle when the Cullens suddenly see themselves on the floor with their place being destroyed and that half an hour has passed adding that Krystal is gone. After failing to find her, the Cullens received a visit from Nahuel that his half brother Jonathan, along with Miley Ray, Krystal’s tormentor, now a vampire by Jonathan, has Krystal. The reason why Jonathan is doing it is because he wants revenge against Lucas for killing Olivia, from the previous story where the Volturi told him leaving out that what Lucas did was unintentional, by Krystal so that Lucas will suffer the same way Jonathan has. The Cullens also find out that Miley sent an army of newborn vampires attacking the Cullens and then uses her mental sharp jabbing gift to knock them out. Then she finally erases their memories of the events that has happened.
The Cullens and Jacob are in Seattle where Jonathan and Miley were spotted. Esme went with Carlisle where they were encountered by the newborn vampires and were saved by Emmett, Alice, Rosalie and Jasper. They arrived at the abandoned factory with the rest of the Cullens where Lucas found Krystal and Jonathan. After the Cullens destroyed Jonathan, Lucas changes Krystal into a vampire after she was on the verge of death from being tortured and fell landing on her head. Krystal wakes up from her transformation where she goes out for her first hunt and Krystal became part of the family.

While Jalen went off to find Tiffany, the Cullens and the Detroit coven hide themselves from Steve and Spike who knows about the existence of vampires. After those two were gone and the Cullens asked Mordecai for directions to the airport, Mordecai questions them and insults Renesmee and Lucina causing tension between the two covens and the Cullens left Mordecai and his friends.

Lucas went in to save them with Edward’s assistance and the two rescued them successfully as Esme tells them to never do that to her again. Lucas’s action has earned the respect from Mordecai and his friends as they offered them to stay at their place. When they arrived, they found Tiffany kissing Jalen which causes tension between Jalen and Mordecai making Jalen go outside upset with Tiffany behind him.
During that, Steve and Spike showed up and discovered Tiffany when Jalen ran back inside without knowing he left her behind.
