Sophia Peletier

Sophia Peletier is a main character and a survivor of the outbreak in AMC's The Walking Dead. She was the daughter of Ed and Carol. During the initial outbreak, Carol, Ed, and Sophia evacuated to Atlanta for safety, but ended up joining a camp of survivors. While at the camp, Sophia sparked up a friendship and eventually a relationship with both Carl Grimes and Niall Ross.

Overview
Sophia Peletier was a shy, quiet and smart young girl. Although her personality was not well shown, it is assumed she was very nice, as stated by Carol in "The Grove", who said that "[Sophia] didn't have a mean bone in her body". It can also be said that she was good at making friends, as she was close to Eliza Morales ,Carl Grimes, Niall Ross, and Jason Ross, who all seemed to care about her deeply.

Death
The Governor stabs Milton in the stomach, intending to have the zombified Milton eat a bound Sophia alive. As Sophia manages to free herself from her binds, a zombified Milton bites her on the cheek, before being put down. Later, she is found by Rick, Daryl, Michonne and Tyreese. Sophia urges the group to kill her so that she won't turn. A tearful Rick Grimes then uses he revolver to shot her in the head with it.

Ed Peletier
Sophia and Ed had a fairly distant relationship, at best. Ed had a history of abuse, beating his wife, both physically and possibly sexually. The same possibly occurred with Sophia, as she seemed to be in fear of him, maintaining her distance from his side. Shortly before the walker attack on the camp, he opted to remain in his tent due to his shame of the injuries on his face due to an assault from Shane Walsh. He attempted persuading Sophia to remain at his side, but Carol berated him. They departed, and Ed dismissed them angrily. Their relationship wasn't explored more before his death.
 * "Why don't you stay here? Keep your daddy company."

Carol Peletier
Carol is the mother of Sophia and she loved her dearly. Carol was very protective of her daughter and is willing to risk her own life in order to keep her safe.

Carl Grimes
Carl was Sophia's closest friend and her first boyfriend. They met when Shane and Lori came across the Peletier family outside of Atlanta the night the military bombed the city. As both groups joined the other survivors at the Atlanta camp, they spent more time together. They played, studied, and lived alongside each other and so became good friends. Her death deeply affected him and he became cynical as he grieved.

Eliza Morales
Eliza was one of the children living in the Atlanta camp. Sophia often played with Eliza, her brother Louis, and Carl in the camp and it can be inferred that they became close. When Morales and his family leave the camp to search for their relatives in Alabama, Eliza and Sophia shared a brief yet tearful goodbye. Eliza hugged Sophia goodbye, and even gave Sophia her doll as a parting gift between friends.

Daryl Dixon
In the season two premiere, "What Lies Ahead", a quick glance was shown to be exchanged between Daryl and Sophia. It was possible that Sophia had something against Daryl as she looked a little angry when she looked at him or that she just did not like him.
 * "You did more for my little girl today than her own daddy ever did his whole life."
 * —Carol to Daryl about him helping find Sophia[src]

Rick Grimes
Rick and Sophia did not interact much in Season 1 or Season 2.
 * "We'd never go without you and your mom. That's a promise."
 * —Rick to Sophia[src]
