Searching For A Heart by Don Henley played at a low volume on Hershel's radio as Hershel had given Harper a glass of water to drink after Rick had explained everything.

"Shane hurting her cost him everything." Hershel responded quietly once he and Rick were in the kitchen and Maggie was calming Harper.

"He knew what Harper went through and still hurt her." Rick replied.

"She was abused?" Hershel asked, Rick nodding.

"It forced her to run away from her stepfather… she was bruised all over and really thin when Shane and I found her." Rick explained, Hershel turning horrified.

"That poor child…" Hershel responded quietly.

Maggie pulled a blanket over Harper, who had drank the water and fallen asleep… and Maggie saw the scars on Harper's right shoulder, Maggie letting a barely audible gasp out as she knew from the serrated edges that they were from a knife.

Andrea kept watch from the RV, fuming still from last night, before spotting a Jeep.

"Holy hell…" Andrea muttered as Glenn climbed the ladder.

"Poachers?" Glenn asked.

"Get everyone to arm themselves, there's someone driving that Jeep." Andrea responded.

Glenn climbed down and ran to the house, walking in and Rick, Hershel and Maggie looking at him.

"Andrea just spotted someone driving a Jeep." Glenn said.

Harper opened her eyes and reached for the revolver, Rick gently stopping her.

"Not the best time, kiddo." Rick replied before he and the others left and she saw Carl walk downstairs.

"Where are they going?" Carl asked.

"Go upstairs, lock the door." Harper responded, Carl doing so.

Harper went looking for any kind of weapon after they left… and found a Beretta 71.

Taking it, she headed to the opposite end of the farm and jumped the fence at the same time that the Jeep had stopped.

"Damn it!"

Harper swore she was imagining things… but the second she and Amber saw each other, Amber got out.

Ignoring her injured leg, Harper ran to her before they hugged.

"I'm back, kiddo." Amber said.

"I thought I'd never see you again." Harper responded as they let go and Amber saw her injuries.

"Who do I have to bash?" Amber asked.

"Actually… Shane's dead. He held me at gunpoint and hit me and… I stabbed him." Harper admitted.

"You did the right thing. He would have killed all of you." Amber said.

"As far as the others know, Shane took off." Harper responded before they heard "Put that gun away!" and "Damn it, Dixon!", the two crouching down… and seeing Daryl and Andrea.

"How can we be sure she ran this way?!" Andrea asked.

"Who else do you know wears converse hi tops? Kid needs some winter boots or her little feet will turn to frostbite." Daryl responded.

"Should we show ourselves?" Amber whispered.

"Slowly…" Harper responded before they stood up, weapons in their jackets and safeties on… and Daryl and Andrea calming down.

"You were in that Jeep?" Andrea asked.

"I thought I saw someone walking along the highway, wounded… she was looking for them too but they took off." Amber explained.

"Harper, you okay?" Daryl asked.

"Yeah." Harper responded.

"I'm gonna go get my stuff." Amber said before walking back to the Jeep.

Once they headed back to the farm, Harper got out of the Jeep and ran to Rick before they hugged.

Amber got out and everyone else's eyes widened in shock.

"What? You never seen a crossbow redneck with two dogs?" Amber asked.

"We were thinking we wouldn't see you again." Glenn responded as Amber looked around for Dale.

"A walker ripped him apart…" Rick explained, Amber turning horrified.

"I'm guessing I missed out on a bit since I left." Amber said.

"You have…" Andrea replied before the others headed into the house to eat.

As Harper started to follow them, Andrea stopped her.

"What happened in that field?!" Andrea questioned quietly.

"Shane went off and then he took off. Daryl was right, Shane broke this group." Harper explained.

"Actually it was Amber who said that, that's why she left." Andrea said.

"And it was you who splintered us further by driving Beth to slash her wrist, you little bitch!" Harper responded, Andrea's eyes narrowing in anger as she saw Harper's bandaged fingers… and she realised that Shane was no longer alive.

"You killed him?!" Andrea yelled.

"He was gonna kill me! I went out to that field with him to talk, thinking I could trust him and calmly talk him out of whatever he was going to do next, Andrea! But when I saw that gun, there was no talking to Shane because he wasn't the Shane Walsh I knew!" Harper responded angrily, Andrea seeing her bruised face and cut lip clearer now after she let go of Harper's wrist and Rick ran outside to them.

"Back off, Andrea!" Rick replied as he shielded Harper.

"You and Lori took in a murderer, Rick!" Andrea responded.

"My daughter was defending herself! Shane swore that Harper would come back safe but he was intending on killing her!" Rick replied, Andrea about to reply when Amber walked and punched her.

"Back the hell off or the last thing you will see is my spiked bat!" Amber threatened.

Rick guided the girls into the house, Amber and Harper hugging each other… and Amber saw the exhaustion in her eyes.

"You should go and rest." Amber said.

Harper nodded and headed outside to the tent, unzipping it and hearing something that made her head snap up.

She grabbed her binoculars and looked through them… and her eyes widened in shock.

"I killed you…" Harper whispered before she ran back into the house and closed and locked the door, Rick seeing terror in her eyes and running to her. "He's out there." She responded, Rick taking Andrea's sniper rifle and unlocking the door.

He headed outside and looked through the scope… and he saw Shane.

He took the shot and Shane fell… and Rick realised that what Jenner had said was true.

Rick walked back in and closed the door, locking it and setting the rifle aside before finding Harper upstairs in the hallway.

"How the fuck did he survive?! I stabbed him repeatedly even after he stopped breathing, Daryl forced me to stop!" Harper responded in panic as Rick crouched down and rested his hands on her shoulders.

"Harper, Jenner told me that we're all infected… whatever it is, being bitten or killed in this case triggers it." Rick explained.

"Whoever dies without being bitten, if their brains are left undamaged… they turn into those things? The military didn't know that when they turned Atlanta into a fireball… they were just aiming blindly." Harper responded, which startled Rick.

"They dropped bombs into the city?" Rick asked.

"We ran through the woods when we heard the helicopters… everything went to hell." Harper responded as they stood up, Rick guiding her into a guest room and getting her to lie down after she pulled her shoes off.

"You haven't been sleeping much…" Rick replied as he tucked her into the bed.

"Every time I try, my mind just goes back to that night." Harper responded as Rick lightly brushed her hair back.

He had to figure out how to tell the others.
