Once Sam finally woke up, he couldn't remember anything between Stull Cemetery and waking up in the panic room. Dean took the lead in encouraging the belief that Sam wasn't around at all the past year, giving Bobby a warning look not to contradict him. Mack had no problem with not saying anything that could potentially cause the wall in Sam's brain to crumble. After what happened, she'd opted to not talk for a while. Sam was mostly eating or sleeping most of the day following his initial awakening. He had been surprised to learn that not only were Bobby and Mack alive, but Cas was, too.

When they got word of a case, Sam jumped on tagging along, which caused Bobby to volunteer to stay behind with Mack. The case ended up being about dragons. Sam and Dean managed to steal a good chunk of the dragons' gold, as well as a book they found in the sewers with the rest of the loot. Dean had found out Sam tricked Cas into telling him about the last year- what the angel knew of it- which included what happened to Mack during her time with John. Sam had expressed remorse for his initial reaction to finding out, but Dean had refused to dwell on it.

When Bobby looked through the book they found, he discovered a few interesting things; one, it described Purgatory and how to open a door into it which the dragons seemed to have taken the instructions for, and two, it talked about the 'mother of all'. So, they had that to figure out. The next case they worked, Sam had worked before when he was soulless. Which immediately sent a red flag up for Dean. He wanted to get out of there before the wall in Sam's head could get further damaged. Sam talked him into staying to solve the case, but there were consequences.

Just like Dean had been worried about, the wall was cracked in Sam's head a little more by the end of the case. He went back into another coma back at Bobby's. Dean was even more worried the next time Sam woke up, even though the younger Winchester played it off as being fine. After that, they worked a ghost case where the deceased was haunting a bunch of mannequins and killing off the guys responsible for her death. It turned out she was tied to her sister, who'd gotten one of her kidneys and it ended with the sister's death. That one didn't feel like a win in theWinchesters' book.

The following case, Balthazar sent Sam and Dean to an alternate universe as decoys to distract one of Raphael's best soldiers. In it, they were actors on a TV show, Supernatural, about their lives. Dean was named 'Jensen Ackles' and Sam was something called a 'Jared Padalecki'. The worst part (for Dean) was that there was no evidence of Mack anywhere in the plot of the show. It was like she just never existed. So, naturally, when they were reunited with her and Bobby back in their world, he had given her a big hug and reminded her how much he loved her.

They were currently working a case with Bobby involving a bunch of dead truckers. Rufus ended up showing up to the same case. So, the group of five (including Mack) ended up following the leads to an abandoned cannery. "Stay close to me, bug," Dean instructed his daughter. Bobby and Rufus took lead, followed by Sam with Dean and Mack bringing up the rear. None of them noticed the man following them in at a distance. As they crept through the halls of the cannery, a door opened and Gwen Campbell stepped through it.

"Gwen?" Dean asked in surprise. "Dean," she greeted him. Samuel walked through the door next, and Dean walked forward, raising his gun. "Welcome to next time," he growled. Sam reached out, lowering Dean's gun, "No, no, no, no! Hold on!" Dean gave his brother an incredulous look. "I said I'd kill him!" Sam gave him a pointed look. "Look, just a second." Rufus raised an eyebrow, "I take it you know each other."

"He's our grandfather," Dean spat in disgust. "Oh. Somebody needs a hug," Rufus quipped. "Why are you here?" Bobby addressed Samuel. "We're working. You?" Samuel asked. "None of your damn business!" Dean snapped. "Sam, take Dean for a walk," Bobby ordered. "You got to be kidding me," Dena muttered. "Look, Dean, it's fine," Sam said, grabbing his elbow to lead him away. "How?" The brothers stepped out of the room. "What is wrong with you?" Dean asked. Sam sighed, "Look, maybe he knows something."

"You don't remember what he did. I do."

"I know. I'm not saying don't. I'm saying not yet." Sam stepped back into the room, leaving Dean fuming outside. As he was standing there, another figure emerged from the shadows- the man who'd followed them in. "Hello, son," John Winchester grinned at him. "Is the bitch in there?" Dean glared back at his father, flexing his fist at his side. "She's not a bitch," he snarled through clenched teeth. "No? Because I seem to recall her having no objections to it," John grinned wider. Dean didn't respond, instead throwing a right hook and clocking his father across the face. "Down to business then," John nodded, flexing his jaw. "I can respect that. Don't think I've forgotten my promise."

"Don't think I've forgotten mine," Dean countered. Just like back at the alley, the pair began to fight, throwing punches and beating each other up. And just like the alley, Dean ended up on top of his father with his hands around his neck. "You. Will. Not. Touch. Her. Again," he snarled, cutting off John's airway. John attempted the same maneuver he used to reverse their positions before, but this time Dean was ready for it. As soon as he felt himself going down, he twisted so instead they rolled and John ended up still on the bottom. Momentarily stunned by the action, John was helpless as Dean tightened his grip on his neck.

Dean glared down at him as he struggled for air, clawing at Dean's fingers. "Screw you, bastard," Dean hissed. "You can rot in hell." John's eyes fluttered and then his body went limp, his hands falling to his sides. Dean straightened up, breathing heavily as he stared down at his dead father. He turned his head, looking over to find Gwen staring at him in shock. "I… I came to ask if it was true," she stammered. "What?" he asked. "Did Samuel really try to-"

"Kill me? Yes. He didn't even blink. That's the guy you're rolling with." Gwen swallowed, glancing at John's dead body. "W-why did you…?" Dean smirked, giving a single, sinister laugh. "Kill my dad? He screwed my daughter." Gwen gulped, biting her lip, "Dean, are you… are you feeling okay?" Dean nodded, "I feel great. In fact, there's something else I need to tell you." Gwen furrowed her brow in confusion. "What?" Pulling out his gun, Dean shot Gwen in the heart and took off running. The others rushed in at the sound of the gunshot, finding both bodies.

Bobby checked Gwen's pulse while Sam checked John's. Mack was staring at John's body, mouth agape. Bobby looked at Sam curiously, and he shook his head, straightening up to go find Dean. "See if you can plug up that hole, Bobby," Rufus said. As soon as the bullet wound was secure, Rufus started chest compressions. "Come on, girl! Come on! Come on!" Bobby shook his head, "She's gone." Rufus fell back in defeat. "Ah, damn it," he swore. Bobby looked up at Samuel, "I'm sorry… If you care."

"Screw you, I care," Samuel spat. Mack was still staring at John in shock. Sam came back, staring at the two bodies. "Is she, uh…" he started to ask. "Where's Dean?" Rufus asked him. "I couldn't find him. Whatever got into those guys must have gotten into Dean." Mack tore her gaze from John, looking up at her uncle. "Daddy's missing?" she asked softly. "We'll find him, Kinley," he reassured her. "Rufus, help Samuel move her and John somewhere. Sam and I will lock down here. We're gonna want to find Dean before he finds us," Bobby ordered. "We're gonna find him alive, Samuel," Sam gave his grandfather a pointed look, "or I'm gonna put a bullet in your head."

Mack whimpered and Sam held his hand out to her, "Come on, Kinley." She hesitated for a moment, and then took his hand. They followed Bobby, locking doors and searching for Dean. Sam kept a firm grip on Mack's hand, using his other hand to dial Dean. They all hurried off when they heard Dean's phone ringing, Rufus spotting him first. "Dean, put the damn thing down," he instructed. Dean didn't listen, keeping his gun raised. Samuel ran over, aiming his own gun at Dean and Dean turned his gun toward him. "Dean, put it down," Rufus repeated. Mack was hiding behind Sam's leg, peeking out to watch.

"You're the least of my worries, Rufus," Dean told him. "Hey, hey, hey, hey," Sam protested. "Okay, both of you," Bobby added. "Both of us, my ass." Dean glared at them all, "I'm not in the mood. I just had a twelve inch… herpe crawl out of my ear." Sam blinked, "What?" Dean continued, "You heard me. I just woke up on the ground, just in time to see this- this… worm thing sliding out of my freaking ear and into that vent." He nodded his head at the nearby vent. Mack whimpered, clinging to her uncle's leg. "So you tell me what the hell's going on!"

"You killed Dad and Gwen," Sam replied. "That's what's going on." Dean frowned, "I remember killing Dad… But the last thing I remember was talking to Gwen in the hallway. The thing must have jumped me." Sam blinked, "You remember killing Dad?" Dean nodded, "I promised him the same thing I promised this son of a bitch. Next time I saw him, I'd kill him." He and Samuel glared at each other. "Alright, we got more pressing issues. Like a monster that gets in you," Bobby interrupted. "Yeah, it's like a Khan worm on steroids," Dean said, still glaring at Samuel.

"You mean like a parasite, something that took over your body," Sam translated. "Monster possession?" Rufus asked. "That's novel." Samuel growled at Dean, "Or that thing's still in you, and we can't trust a word you're saying." Dean protested, "It's not!" Bobby frowned, "Check your ear." Dean looked over at him, bewildered. "What do you mean, check my ear? Check my ear for what?" Rufus walked up, sticking his finger in Dean's ear. "Hey! What? Why don't you buy me a drink first?"

"Second date," Rufus quipped back, looking at his finger. "Oh, yeah, we're goo positive." Dean was still looking at him in bewilderment. "What does that mean? What does that mean?" Rufus looked back at him, "That means it was in you, alright." Samuel scowled, "Or it still is." Dean glared back at him. "It's not in me!" Mack whimpered again, and Sam put a comforting hand on her head. "Okay, everybody give up your guns," Bobby said. "What?" Samuel snapped. "Whoa, whoa, whoa, whoa, think about this for a second, Bobby," Rufus protested. "I'm thinking we don't know who is and who ain't got the damn Khan worm up inside his melon."

"It's not in me!" Dean shouted again. "I didn't say it was," Bobby said. "Point is we don't know who it is. It could be any one of us. So the best we can do… is make it that much harder for that thing to blow our fool heads off." Bobby put his gun into a sack, then held it out for the others to do the same. Dean, Sam and Rufus all complied and placed their guns into the sack grudgingly. "You waiting for a handwritten invitation, Campbell?" Rufus asked. Reluctantly, Samuel followed suit with his own weapon. They all headed into the back room and locked the sack of guns in a locker.

"Okay," Bobby nodded once the guns were locked up tight. "We need some time to breathe, make a plan." Samuel scoffed, "A plan? Based on?" Bobby glared at him, "I'm gonna make a few calls, see if anybody ever heard of anything like this." Rufus nodded in agreement, "Hmm. Ditto. Got a few trees I can shake." They both headed off a little ways to make the calls. Mack was still clinging tightly to Sam, eyes wide with fear. "It's okay, Kinley," Sam murmured, running his hand through her hair. "Everything's going to be alright."

Samuel snorted, "Don't lie to the girl. We're all screwed. You shouldn't have brought her here." Dean glared at him, "Yeah, well, I wasn't about to leave her alone, so didn't have much of a choice." Samuel rolled his eyes, moving toward the door. Sam moved to block his path. "Relax. Bathroom break. So unless you want to hold it for me…" Sam moved aside, but he and Dean followed at a distance. They were waiting as soon as he got out of the restroom. "What?" he glared at the brothers. "Nothing. I'm just wondering how you sleep at night," Dean quipped.

"Like a baby. Thanks for asking." Dean scowled, "You fed us to Crowley." Samuel nodded, "True, but what am I gonna do about it now? Do I blame you for wanting to kill me? Of course not, Dean. What I did was… but I'm not apologizing. I did what I did. I don't cry over spilled blood." Sam shook his head, "So you can really just go on, like…" Samuel cut him off. "Just because you're Dr. Jekyll at the moment doesn't mean you can get all high and mighty. Don't forget, we spent a year together."

"Yeah, we did. We're blood. And you still sold me out," Sam glowered. "Trust me, what I did pales in comparison to what you did, and on more than one occasion." Sam stepped forward, leveling with his grandfather, "Alright, tell me what I did." Dean immediately protested, stepping between them. "No, Sam, come on," he said, then looked at Samuel. "The only reason you're alive right now is because we're working a job. The minute we kill this thing… you're next."

"Okay, then. We'll just see." Dean spotted goo coming out of Samuel's ear and managed to grab his arm and angle it up right as he pulled a gun and shot. He shoved Sam and Dean against the lockers, taking off running. "D-Daddy," Mack gasped. Sam and Dean both looked over. Samuel's bullet had ricocheted and hit Mack in the shoulder. "Bug! Oh, I'm gonna kill him!" Bobby and Rufus rushed in. "I heard a shot," Bobby announced. "Samuel!" Dean growled. He had torn off part of his shirt and was holding it against Mack's wound. "I'm gonna need my gun back now, Bobby," Rufus told him. "You think?" Bobby asked. "Yeah."

They headed back for their weapons. "I got her, Dean. You go kill that son of a bitch," Sam said. "Alright," Dean nodded, kissing Mack on the forehead. "Don't go anywhere and call if you see something." Sam nodded, taking over holding the piece of fabric to the wound in Mack's shoulder. Bobby, Rufus and Dean headed off, sticking together. "Uncle Sammy, it hurts," Mack cried, tears streaming down her cheeks. "I know, Kinley. The only way to get it to stop is if I took the bullet out." She whimpered, face scrunched up in pain. "Do you think you can be a big girl for me while I take it out? It'll hurt." She whined a little, but nodded her head.

"Alright. Hold onto that tight for a minute," he placed her hand on the fabric. She did as she was told, holding the strip of cloth in place while he took out his to-go tool kit and grabbed a pair of tweezers. "Okay. Deep breaths, alright? I'll be as fast as I can." She nodded again, whimpering again as he removed the blood-soaked fabric. He had her sit down so she was stable, and then he went in with the tweezers. Luckily the bullet hadn't gotten lodged very far in, but it was still difficult to reach easily. Mack cried out as he dug into her wound.

"Shh. It's okay, Kinley. Just take some deep breaths for me. Just like we taught you. In through your nose, out through your mouth, slowly." She took a few breaths and then cried out again in pain. "Almost got it," Sam murmured gently. "You're doing so great, Kinley girl. Just keep breathing." He finally got a good grip on the bullet, pulling it out of the wound. Mack sobbed as he dropped the bloody bullet on the ground and ripped a fresh strip of cloth off his own shirt. "Shh. It's okay. It's over now. You did a good job, sweetheart. You're so brave." He tied the cloth around her shoulder to stop the bleeding, pressing his lips to her head.

Bobby, Dean and Rufus came in carrying Samuel's dead body. Well, Bobby and Rufus were carrying the body- Dean was in handcuffs. "What happened?" Sam asked. "Dean shot him. Rufus and I are heading out to the cars to grab some tools. Keep an eye on each other and if you see the worm, kill it." Bobby and Rufus exited. "She alright?" Dean asked, looking at his daughter. "Yeah, we got the bullet out. We can clean and dress the wound properly once we get done with this. What's with the cuffs?"

"Bobby and Rufus thought it was best until we figure out if the worm really is still inside Samuel," Dean shrugged. Sam nodded, glancing at his grandfather. "I barely remember him, and what I do remember- it's not good. And what he did to us… But…" Dean raised his eyebrows. "There's a 'but'?" he questioned. "I mean, I just can't help but think… What would Mom say? Killing him… killing Dad…"

Dean scowled. "You know what I think Mom would say? She'd say just 'cause you're blood doesn't make you family. You got to earn that."

The lights came back on and Rufus and Bobby entered the room again. "Well… alright," Rufus announced. "Let's play operation." Bobby handed Sam a first-aid kit for Mack. "You boys want to take a breather?" he asked. "We're good," Dean answered. "We're about to crack open your grandpa's grapefruit. Take a breather." The Winchesters all stepped into the hall, and Sam set to work cleaning and redressing Mack's wound. As he was finishing, Dean got his attention. "Sam." He looked over, seeing Samuel- alive- blocking the door so they couldn't get back in.

Inside the room, Bobby threw Samuel against a frayed cable, electrocuting him. The Khan worm came out of Samuel as Sam and Dean kicked the door in. "Bobby, you okay?" Sam asked. Dean headed over, waking up Rufus. They both helped the elder hunters to their feet. "This can't be my afterlife 'cause you four are here," Rufus quipped. "What happened?" Sam shook his head, "Well, when we left, he was dead on the table." Bobby nodded, "Yeah, till he wasn't." Rufus frowned, "So how did he get double dead?"

"Bobby threw him against that," Dean gestured to the wire. "I guess it was a live wire. It shorted, and he went ape. Then that thing crawled out of his ear." Bobby frowned, "At least we know what tickles it. Electricity." Sam nodded in agreement. "Yeah. Now the question is, where'd it go? You see?" Dean shook his head, "No." Sam gestured to Bobby and Rufus. "You two were down for the count." Dean nodded, "Yeah. Well, it either bailed or it's in either one of you."

"Or, it's in one of you," Rufus eyed the Winchesters. "No, we were awake." Rufus narrowed his eyes. "Did you have eyes on each other?" Dean nodded, "Yes." Rufus pressed, "A hundred percent of the time?" Dean paused. "Define a hundred." Rufus nodded, "Like I said." Sam sighed, "Alright, how about, uh, check for goo, right?" They all put their fingers in their ears, coming up negative. "The girl, too," Rufus nodded at Mack. "Come on, she's a kid," Dean protested. "I don't think it matters to that thing, Dean," Sam grimaced. Mack reached up, sticking her fingers in her ears just like the adults, coming away clean, too.

"Told you," Dean grumbled. "It might just be gone," Bobby suggested. "No," Sam shook his head. "I think it might have wised up and covered its trail." Dean scowled, getting the wire, "Alright, let's settle this one hundred percent." He stripped the cable, plugging it in. "We're live." He started by putting the wire to Samuel again, nothing happening. "Alright. Yeah. I'll go first." He took off his jacket, shocking himself with the wire. "Son of a- whew. Awesome. Who's next?" Sam took off his jacket, rolling up his sleeve. "Go ahead." Dean shocked him and Sam grimaced. "Okay, Kinley."

"What? No," Dean protested. "Dean, we have to. Give it to me if you won't do it." Dean opened his mouth to protest further, then handed over the cable reluctantly and turned away. Sam crouched down in front of Mack. "This will only hurt for a second, okay, Kinley?" She nodded, "Okay." Pursing his lips together, Sam put the wire to her skin. She yelped jumping and Dean closed his eyes against the sound, jaw clenched, but didn't turn. "That's it. All done," Sam assured her. "Okay, Rufus, you're up."

"Uh, whoa, whoa, whoa, whoa. Uh, no, I'm sorry, I'm sorry," Rufus shook his head. "No passes, Rufus. Come on." Rufus backed up a step. "I got a damn pacemaker." Sam grimaced, "Well, you better hope it's a good one." Bobby looked at Rufus curiously, "Since when do you got a pacemaker?" Rufus glared, "Since Bush Jr., term one. I'm down three toes, too, FYI. Alright, come on. Just make it quick." Sam put the cable to his arm. "God! God! Damn it! Damn it!" Sam stopped shocking him. "You okay?"

"No, I'm not okay. Give me that," he snatched up the cable. "Okay. Alright, my turn," Bobby said. "Well, it ain't inside me, so go right ahead." Rufus stepped forward and Bobby took a step back. "Alright, then just stand still, Bobby," Rufus told him. "Okay, sure." Bobby took another step back to counteract Rufus. "I'll make this quick," Rufus assured him. "No problem." They continued the dance. "Alright? Let's do this," Rufus said. "Okay, uh, just a second, Rufus."

"Just a second nothing, whatever you are."

"I'm Bobby!"

"Bobby, my ass." What happened next was too fast for Sam or Dean to react. Rufus took another step toward Bobby and Bobby whipped out his knife, stabbing Rufus in the chest. "Bobby!" Sam cried, helping Rufus to the ground. "Rufus." He and Dean moved to stand between Bobby and Mack, protecting her. "Bobby, there are two of us and one of you." Sam caught a hold of Bobby and Dean punched him, knocking him unconscious. They tied him up using duct tape.

"Well, hey, there, you little herpe," Dean greeted when Bobby woke up. He put the cable to Bobby's neck. "Why do you keep talking about herpes?" Sam asked. "What? I don't. Shut up. Shut up," Dean went back to addressing the worm inside Bobby. "Now, don't even think of shagging ass out of here, 'cause we got every crack in this room sealed. So get comfy." Bobby glared up at him, his voice coming out double as the worm spoke through him. "I am comfy. It's nice in here. And you love this guy, don'tcha? You really want to kill him and take him with me? Haven't you lost enough pals today?"

"We'll do what we have to. And we got some questions for you, so you can either play ball, or we could fry up a little shrimp on the barbie." Bobby smirked, "Ask. Been waiting for you to ask." Dean raised an eyebrow. "What the hell's that supposed to mean?" The creature chuckled. "It means I got nothing to hide."

"What are you?"

"You haven't got a name for me yet. I'm new around here. Eve cooked me up herself," the creature replied. Dean held the cable to Bobby's neck again. "Who is she, this Eve bitch?" he demanded. The mother of all of us, and the end of all of you. By the time she's done, there'll be more creatures than humans. You'll live in pens. We'll serve up your young and call it veal." Dean grimaced, glancing over at where Mack was sitting and waiting for them to save Bobby. "And what's your deal in all of this?" Sam questioned. "I mean, how's jumping a few truckers gonna help?"

"You think I'm here to mess with a couple Cannery workers? We led you here," the creature informed them. "Why?" Sam asked. "She has a message for you." Dean swallowed, "Oh, yeah? What's that?" A grin spread across Bobby's face. "You're all gonna die. She's pissed. She's here. And it's gonna be nothing but pain for you from here on in." He began to laugh. "Well, here's my response." Dean pressed the live wire to Bobby's neck once more. "Dean. Dean!" Sam stopped him. "How much more do you think he can take?"

"You can't kill me," the creature taunted, "not without taking him with me." Dean inhaled deeply, "Well… we'll just have to do what Bobby would want us to do." Sam wrapped Bobby's ears and mouth in more duct tape. "No way out, slug-o," Dean drew his mouth in a thin line. "Bobby, hang in there." He put the cable to Bobby's neck, holding it there until Bobby sagged forward. "Bobby?"

"Is he, uh… Hey, hey," Sam began to unwrap the duct tape, and the worm fell out of Bobby, dead. "Whoa. Bobby." Bobby didn't respond. "Bobby, hey," Dean called out. "He's not breathing," Sam said. "Bobby!"

Bobby had survived- barely. When they were burying Rufus, Dean decided that they would all start with a clean slate right then and there with a blanket apology for all the crap any of them had ever pulled. They'd need it if they were going to move forward and stop Eve from using her monsters to take over the world.
