A New Life

Emmett meets Lucas.
Eight years later in A New Life, Emmett 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. Emmett gets challenged by Lucas where apparently Lucas wins easily much to the family’s amusement but none of the less, Emmett thinks Lucas is a good person. He along with the Cullens and Jacob agrees 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. Emmett, Edward, Lucas and Jacob then caught May and Niall from outside calling the shots and find out that they work for Aro and the Volturi who are were the ones who kidnapped Renesmee and 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 and Emmett has to restrain Lucas from going back until Lucas mysteriously goes 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. Emmett, 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

Emmett and his family see that Lucas is depressed and the reason for that is because he is the only one who doesn’t have a mate. Emmett goes to school with Lucas and his family where she sees that Lucas is in love with a girl Krystal Diamond. When Krystal asks Lucas to have lunch with her, Emmett answers for Lucas to his amusement much to Lucas’s annoyance.

The Cullens then hear that Krystal’s father Roark Diamond was killed which turns out to be a vampire. Soon they see that someone is after Krystal and they move Krystal into their home after talking to the principal to allow Carlisle and Esme to be Krystal’s guardian so that she doesn’t move to New York.
Weeks later, the Cullens were trying to deal with the disappearances of many residence in Seattle where Emmett was teasing Lucas and Krystal of their little “moment” and Lucas was about to fight Emmett 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 killing 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 even by passing Bella’s shield. Then she finally erases their memories of the events that has happened.

They arrived at the abandoned factory with the rest of the Cullens where Lucas found Krystal and Jonathan where Emmett helps out Edward, Bella, Jasper and Jacob ripping Jonathan’s body and burned him.
