Carphia

Carphia is the het ship between Carl Grimes and Sophia Peletier from the The Walking Dead fandom.

Season 1
On the night of the military bombings in Atlanta, Carl and Sophia, being the only kids, are seen playing checkers together in the back of the Peletier's van while stuck in a traffic jam. Sophia tells Carl she thinks his "dad" is nice, but Carl corrects Sophia that Shane is not his dad. Throughout their time in the series together after this they are shown to study and play games with each other.

At the Atlanta camp, Carl and Sophia are playing in a wooded area before noticing a walker eating a deer. They scream and call for their moms while running back to the camp. Carl and Sophia are later seen studying with the help of their mothers, Lori and Carol. When Shane asks the kids if they want to help clean some fish. Carl, excitedly, calls Sophia to come with him and Shane.

On the way to the CDC, after they leave Jim, Carl and Sophia are sat next to each other in the RV, looking out the window, sadly. At the CDC, Carl and Sophia are playing checkers in the recreation room. Carol tells them it's bed time and states that this might be the first time they might get real sleep.

Season 2
After escaping the CDC and heading back to Atlanta, Lori reminisces on a time where she, Rick and Carl went to the Grand Canyon. But, since Carl was so young he doesn't remember the trip and asks if they can go again now that he's older. Sophia then asks if she could go too, to which Lori reassures her they won't go without her or Carol, to which Sophia smiles and lays her head on Carol's shoulder.

After Sophia goes missing on the highway, Carl is adamant that he's going to search and find her. While searching for her, he gets shot in the side.

After Carl wakes up from the surgery to remove the bullet in his body, the first thing he asks is if Sophia is okay. Rick lies and tell him she's fine so he could get some rest, Lori later tells him the truth. After he recovers from his wound, Carl sneaks a gun from the RV and when he gets caught he says he wanted to defend the camp and look for Sophia. Carl gets irritated with Shane's mentality surrounding Sophia's disappearance, saying she isn't dead and that they'll stay at the farm until they find her.

After Rick, Hershel, and Jimmy come back with new walkers to put in the barn, Shane gets angry and shoots at the walkers in vital spots to prove they aren't actually alive. He then busts open the barn full of walkers. After they think they've killed them all, Sophia emerges from the barn, as a walker. Carl is seen crying while Lori holds him and Rick puts Sophia down. Shortly after, Lori and Carl are sitting next to the barn. Carl states that he wanted to be the one to find Sophia, and that maybe she was hiding in a cave or tree. But, then Carl expresses that he thinks Rick did the right thing by shooting Sophia and that he would've done the same thing.

Carl is seen mourning Sophia at her grave. Carol attempts to cheer him up by assuring him that they'll see Sophia in heaven again one day and that she's in a better place, to which Carl denies, saying she's not in a better place and that heaven is another lie, he calls Carol an idiot before storming off.
