When Brittany went to her shared room, she didn't find them however, something that was hanging from Alvin's bed caught her eye. She approaches it and smiles. "Hey it's you" Brittany grabs the the thing which was her pink vest. "Now what were you doing in Alvin's bed?" She questions herself. "I always had it with me every time that I slept because it reminded me of you and the perfume you used" Brittany hugs her vest and says "aww really? That's so cute and because I love you, I'm going to let you keep it" she then puts it back on his bed before walking away. "Thanks baby, I'll treasure it forever" Alvin responded.

Brittany went to check the living room but didn't find the two, however, she started to hear voices coming from the back door of the house. She approaches the door and sees Simon outside holding what looked to be a controller and Jeanette was adjusting its antenna. Brittany comes out and questions them, "hey guys, what are you doing?" the two turn to look at her. "Is this Brittany speaking to us or is it you Alvin?" questioned Simon. "It's Brittany, anyway what are you two doing?" She asked as she notices something on the ground in front of them. She looks at her tombstone with a bunch of flowers and it said "Brittany Seville born on 1993 died on 2009" will always be remembered" she then saw below the numbers Alvin's signature and to its side it said "I will always love"

both Simon and Jeanette notice Brittany looking at her own tombstone. "Britt, are you listening?" Brittany looks at then before saying "huh what? Oh sorry, what were you saying?" She questioned. The couple look at each other and Simon tells her "I was saying we are using this controller that tells me how deep the casket that has your body is buried so, what I'm planning to do is to retrieve the casket and get your body out, then ill try to replace your bag organs with artificial organs but in order to do this, I'll need Alvin's help" Brittany looked at him with hope and asked "great and I'm curious to what you need Alvin for?" Simon hands the control to Jeanette before saying "because, with his help, I will be able to preform surgery on your body, look you'll understand soon enough" Brittany responds "oh alright, I'll be in the living room if you need me" she heads back inside leaving the two.

Brittany entered the living room to see Dave in his pajamas. "Um Brittany or Alvin it's time for bed and where's Simon and Jeanette?" Dave questioned. "Oh, they're outside checking something" Brittany responded as she sat on the couch. "Oh okay thanks, now go bed in either Brittany's or Alvin's bed whoever is ugh... You get what I'm trying to say" Brittany's laughs and before saying "yeah goodnight Dave" she the makes her way upstairs.

Moments later, Brittany felt like she needed to use the bathroom so, she closes her eyes. "Alvin, can we switch?" "Huh oh yeah sure" he replied before taking control once again. "Boy what a day it was huh Alvin" Brittany said before getting out of his body and her spirit stands next to him. "Yeah, and I'm glad that our family finally knows that you're still here" replied Alvin as he leaves the room and goes to bathroom as Brittany follows. "Yep.. oops if forgot that you need some privacy" Brittany giggled before going inside her host and goes deep in to his heart.

After he did his business, he went back to the room to see Simon and Jeanette in their beds, and gets on his own bed. "Goodnight Britt" Alvin whispered. "Goodnight Alvin" replied Brittany in his mind.

The next morning, Brittany woke up Alvin for school since she didn't want Dave to yell at him for not being up early. "Alright I'm up baby" Alvin responded as he hops off his bed to the bathroom to brush his teeth.

After that, he gets out of the bathroom to see Dave in the hallway. "Oh Alvin or whoever is in control, you're not going to school today because of the situation you two are dealing with so, feel free to go back to bed" said Dave before walking away. That was like music to Alvin's ears and starts to rejoice "did you hear that Britt? We get to stay home from boring school" Brittany who was also happy responds "yes now we can spend the whole day together Alvie" she then gets out of his body and kisses his cheek. Alvin didn't feel it but, was still glad that she was happy like he was.

Alvin goes to the living room and sees Dave leaving with Simon and Theodore. "Have fun in school you two" Alvin said in a mocking way. Simon who wasn't bother by his comment replies "we sure will Alvin" then Dave speaks "Alvin, I'll be back in few minutes so please behave and if you're hungry, you know where the toaster waffles are" Dave closes the door and locks it with his key. "Now this is what I deserve, some piece and quiet, no annoying teachers, no annoying homework, and no annoying brothers lecturing you about school. It just me and the most beautiful girl in the world" Alvin turns on the tv before handing to the kitchen to get some toaster waffles. They spent the day watching horror movies and playing videos games which by the way, they took turns using Alvin's body to play.

Later at night time, Alvin was in his room reading a comic book which Brittany found to be boring however, she didn't want to be rude with Alvin since he's been so generous since yesterday. "ALVIN COULD YOU COME HERE DOWN HERE PLEASE?" shouted Simon from the basement. Alvin lazily slithers out of bed and heads to where his brother was.

Once he gets there, he sees everyone there and hospital equipment. He then sees something leaves him speechless. There in the middle of everyone was the casket that has Brittany's body. Simon struggled to dig and get the casket in the house but he managed to do it. "Good you're here" Said Simon as he approached him. Brittany leaves Alvin body and approaches her original body. The casket was transparent so she was able to see her body that wasn't decomposed much. Her skin was still there but, her body was very bony. "Alvin we are going to need you help with the surgery" said Simon before putting a paw on his shoulder. Alvin looked at him demented and asked "how can I help?" Simon looks back at the others and then back at him. "Remember that demon or whatever that creature was who took over your body?" Alvin nods.

"Well, have you thought that maybe that creature left some of his powers inside you?" Alvin shakes his and Simon continues "could you check?" Alvin looks at him like he lost his mind so he asked "how am I suppose to do that Sherlock?" Simon doesn't answer and gets close him. "PAM" Simon punches Alvin's chest which shocked everyone but, they knew that it was part of Simon's plan. "What was that for Si?" Alvin questions while gasping for air. Simon doesn't answer, instead he elbows Alvin on the back of his neck making him get in his knees. "Si... Cough, what.. Cough is... Cough, the matter with you?" Alvin questions. However Simon still doesn't reply and kicks his stomach instead.

Meanwhile everyone was horrified as they watched Simon assault his brother. Theodore couldn't handle looking at the scene anymore so he runs out of the basement even though he knew it was part of Simon's plan and, Eleanor and Dave ran after him.

Also, Brittany who was standing close to Alvin, wanted to stop Simon from attacking him but, it was useless trying since she that she couldn't even touch him and he couldn't hear her pleas. "What's wrong doll trash? have you gotten weaker over years?" questioned Simon before grabbing Alvin by his collar. Two words that Simon mentioned brought flashbacks to Alvin. Events that took place when he was a toddler. Suddenly Alvin's vision begins to get blurry and in a few seconds instead of seeing Simon's face, he saw his fathers face. "dad?" He questions. Simon realizes that his plan is working so he says "that's right it's me and I know that because of the beatings I gave you when you were a child, darkness was born in your heart so, another personality was born however, after all those years. you managed to get rid of not just your dark personality but, you got rid of your brother Sam. But now I'm back and I'm going to hurt you more than ever however, there is a way that you can stop me, and that is by you awakening the remaining powers that your dark personality left. If you don't awaken and use those powers then, I won't just hurt you, I'll hurt your girlfriend Brittany, her sisters, your brothers and that human guy" Simon was about to deliver another punch but, suddenly he feels heat coming from Alvin.

"IF" Alvin stands up as he stares at the ground. "IIIIIFFFFFFF" he looks at Simon as he begins to breath hard. "IF YOU EVER LAY PUT FILTHY HANDS ON MY GIRL OR MY BROTHERS OR ANY OF THE ONES I CARE ABOUT, YOULL BE REGRET THAT YOU EVEN EXISTEEEEEEEEEEEEEEED" all of a sudden, a familiar red cloud surrounds Alvin and he losses consciousness before lounging at Simon ready to do some deliver some damage however, Simon was prepared for this so, he takes out a tranquilizer gun from his back pocket and delivers a dart on Alvin's shoulder. However it didn't work and he only managed to piss off Alvin even more. Jeanette approaches Alvin but Simon quickly tells her "No Jean stay out of this please" Jeanette wanted to protect her boyfriend but, she knew she could get herself hurt if she interfered. Alvin who has Simon pinned, grabbed takes tranquilizer gun from him and crushes it with one paw and was about to land a very hard punch on Simon's jaw but, fortunately for Simon, Dave came in just in time and grabs Alvin off Simon. "Alvin calm down its me" Dave struggled to keep Alvin still because, his hands were burning due to heat coming from Alvin's body who was just as strong or stronger than he was.

Alvin looked at everyone, he didn't see the face of his loved ones anymore, instead he sees his fathers face with an evil smirk. Finally Alvin manages to break free from Dave's drip and lands hard blow to his stomach. Dave gets on his knees and hugs his stomach as Alvin lands another blow to the side of his ribs. Meanwhile Brittany who was frozen in fear, couldn't handle looking at his family being hurt anymore so, she yells "AALVINNNNNN" suddenly, Alvin stops attacking Dave and looks at Brittany and, is able to recognize her instead of seeing his dad's face.

Brittany had tears in her eyes and says "Alvin please stop, you're hurting our family" slowly Alvin regains his consciousness and looks around to see Dave and Simon on the floor. After a few seconds of silence, Alvin starts to feel guilty. "What have I done?" he questions as he tries to wake up an unconscious Dave. "Alvin it's not your fault, and I'm still not done with my plan so please get over here" Alvin looks at him demented and approaches him as the red could still surrounded his body. Brittany gets closer as well "Simon, what just happened? The last thing I remember is coming to the basement" said Alvin before rubbing his eyes. "You'll know soon enough" said Simon who glances at Jeanette. "Jean, could you try to wake up Dave for me and take him to the living room and then come back? We can't have interruptions and we need as much space as we can get. Oh and here's what you need to change in to before coming back" Jeanette nods as she takes a bag from Simon and whispers "I'll be back soon" she then approaches Dave.

Dave woke up a few minutes later with pain on his temple, and makes his way out as Jeanette helped him. She led him to the living room safely and hands him an ice pack that she got from the fridge. She then goes to the bathroom to change. After that she heads back to the basement and locks the door.

"Good you're back" said Simon as he stood next to Brittany's white casket. All three were dressed as surgeons and each of them had an oxygen tank. "Alright before we begin..." he looks at Alvin and says "when I say go, you're going to release all of your power on the body and you'll try to make it give a heart beat and while you're doing that, I will be placing Brittany's new artificial organs after I have removed her bad organs" Simon points at a box by Alvin's feet. "But Simon I don't know-" "just do it when I say go" Simon interrupted before looking back at the casket. "Alright guys, turn on your oxygen tanks because I'm going to open this now" said Simon as he begins to open the casket. As soon as he did, the smell of Brittany's body filled the area. Simon gently carries the body bridal style to a nearby table and puts it there. He then removes the clothes from the upper body only. "Scalpel" Simon demands. Jeanette hands it to him and he begins to open the body's torso to the abdomen. "napkins" he demands and Jeanette hands it to him. He cleans all of the blood off.

It hurt Alvin to see his girls body going through this so, he looks away and sees her spirit standing next to him. "I love you" he whispers and she replies "I love you to"

Three hours later, Simon took out all of the bad organs the body had and was now ready to put the artificial organs. "ALVIN GO" Simon shouts. "Please body don't fail me now" Alvin said in his mind before he grabs the body's right paw with both of his paws and begins to concentrate. Seconds later, the cloud surrounding Alvin's body was now moving to Brittany's. "Hurry Si, I don't know how much longer I can hold" Alvin said as he kept his eyes closed and his paws still. Simon glances at the heart monitor next to the table and notices that it's working. "Alvin you're doing great so far, so stay like that for a few hours alright" said Simon as he receive the box that was on the floor, from Jeanette. Simon began to place the artificial organs as Alvin kept holding.

An hour later, Alvin felt like his body could give up any second so he warns his brother. "Si I can't hold it anymore" said Alvin as his hands were starting to shake. "YES YOU CAN ALVIN, DON'T YOU DARE UP BECAUSE IF YOU DO, YOU'LL LET BRITTANY DOWN, YOU'LL LET ALL OF US DOWN AND I WILL BE EMBARRASSED THAT I HAD A BROTHER AS QUITER. NOW PELASE DON'T GIVE UP, DO THIS FOR BRITTANY" Alvin glances at his girlfriend standing next to him looking worried. "He's right, I won't mess this up" Alvin mumbles and turns to look at Simon to give him a nod. Simon smiles then continues to place the remaining organs.

Jeanette looks at the heart monitor to see things were getting better.

2 hours later, Simon finished putting the remaining artificial organs in the body and says "Now Alvin, tell Brittany to get in her body" Alvin glances at his girlfriend and she nods. Brittany gets on the table on top of her body and slowly enters it making it more difficult for Alvin to control his power. "Ugh come Alvin, you can do this" Alvin said to himself.

All of a sudden the ground started to shake, as Alvin was slowly losing control. "Come on Alvin don't give up, do this for my sister" Jeanette cheered for him. Alvin takes a deep breath and with all he had, he manages to increase his power causing Brittany's body to glow red. After a minute, Alvin began to feel weak so he shouts "I CANT HOLD NO MORE GRAAAAA" the red cloud that was surrounding his body was gone and it was surrounding Brittany's instead.

Alvin got on his knees as he breathes hard. No one was talking, it was peacefully quiet, and the ground wasn't shaking anymore. Alvin rose to his feet to look at Brittany's body. It was still glowing with te red cloud but after a few more seconds, the glowing was gone and the red cloud was gone. Now one said anything as they stared at the heart monitor. There wasn't a single heart beat. Alvin got on his knees again and began to sob. "I'm so sorry Brittany, I fa-" he stopped talking when he heard the heart monitor beeping. He gets to his feet again to see that she was still alive. Brittany's body wasn't bony anymore instead it was back to normal. Smiles formed on their faces, as they saw Brittany breathing.

They couldn't hold their happiness anymore so they form a group hug. "I KNEW YOU COULD DO IT BRO" said Simon as he hugged his brother tightly. "Thanks Si, if it wasn't for you're advice, I would've given up and let everyone down also, thank you Jeanette's as well for letting me know that Brittany not only I need Brittany, you and Eleanor do as well" they began cry from happiness. They all took off their oxygen tanks and noticed that the smell was gone.

However their moment was interrupted when they heard someone moaning. Alvin looks at Brittany's body to see her opening her eyes. "Britt?" he questions before holding her paw. She gently squeezes his and says "Alvin" both Jeanette and Simon admire the sight of couple reuniting. "how do you feel?" Alvin asked a he rubbed her forehead softly. Brittany sits up and looks at her familiar paws to see that she was back in her original body. She then looks at Alvin and says "just tired" then Brittany starts to feel cold air on her chest so she glances. "Aaah, Simon where did you put my shirt before you began the surgery?" Brittany covers her chest with her arms making Alvin laugh. Jeanette spots her shirt on the floor and hands it to her. Brittany almost gagged because of the smell the shirt had so she declines. "No thanks Jean, it stinks" Alvin then gets an idea, so he removes his pink sweater and offers it to her.

"Here Britt, wear this" Brittany looks at him only wearing a white t shirt and asked "are you sure Alvin?" Alvin kisses her forehead and says "yes I am, and you know what, I want you to keep it since you let me keep your vest, then I'll let you keep my pink sweater" Brittany smiles and accepts his sweater. She puts it on and tells him "I'm so lucky to have the best boyfriend in the world" Alvin winks at her and says "when you're the great Alvin Seville's girlfriend, you can expect nothing but happiness for him to give you" Brittany giggles before asking Simon "so, I guess I'm part robot now" Simon and Jeanette look at each other before he says "um well you're still a female chipmunk, with some artificial organs but, you could say that"

Brittany the looks inside her sweater to look at her chest and realizes something. "Hey, didn't you put stitches in my body when you finished putting my new organs?" Simon says "yeah why?" Brittany looks around her torso again and says well, I don't have any stitches, In fact I don't have any marks that show I had surgery" Simon's jaw drops but then Alvin gets rid of the confusion. "I think it has to do with the powers I used to revive your body, I guess it was also enough to be able to heal your upper body as well" All of them look at him amazed.

"By the way Simon, how did you know that I had powers? and how did you know that it would be a great tool to use for the surgery?" questions Alvin. Simon takes off his glasses and hands them to Jeanette before saying "a few days ago, I found a pieces of paper on the bushes outside and I picked up every piece and put them back together. I know that you read front, however there was something on the back that had a weird message which said use your powers for revenge or for good to fix others mistakes" which meant that when Sam wrote the that message in the back, he knew that Alvin had a dark personality that had powers but, he also must've known that Alvin could control those powers so, that's why Sam wrote that message in the back, to let Alvin know that once he got rid of his evil personality and Sam, he would have the choice of fixing Sams mistakes by of helping the ones he hurt which he did with Brittany, or not use the powers at all. So this all means that Sam knew what he was doing was wrong and deep down he was a bit good in his heart. Also in order for Alvin to use his powers, someone had to help him awaken it by reminding them of their past which is why I attacked you Alvin. And I apologize for that" Jeanette hands him his glasses back and he puts them back on.

"It's alright bro, you were doing it so we could have the tool restore Brittany's body" Alvin hugs his brother. Brittany's gets off her the table and tries to walk. "Ouch, I feel like I have been walking for days" she said. Jeanette gently grabs her arm and puts it over her shoulders. "well, guys I think we should get going because the others must be really worried" Jeanette said. Alvin runs ahead and unlocks the door for the three. Soon they hear foots steps approaching them. There stood Dave, Theodore and Eleanor with tears. "BRITTANY" they run to the chipettes to give her a bear hug. "Ellie, Theo I missed y'all" said Brittany before looking at Dave.

Theodore and Eleanor let go of her as Dave gets on one knee. "Daaaad" Dave picks her up and hugs her.

After a minute, he releases her and she says "well, guys I need to go take a shower which I really need" she then heads to the bathroom leaving everyone. "I can't believe Brittany is with us again, oh this requires a huge celebration so, get ready fellas because tomorrow you all aren't going to school, instead we all are going to the mall to shop for dresses and tuxedos that y'all will need for the prom that I have planed to make next Saturday to celebrate Brittany still being with us. She will be the queen of the prom" Everyone cheers except for Jeanette and Simon. "But Dave, I don't want to miss any assignments" "me neither" said both Simon and Eleanor which annoyed Alvin. "Come on you two don't be such party poopers" Simon and Jeanette ignore his comment. "Both of you down worry, tomorrow I will go to your school to pick up all of your assignment and homework's" Dave said which cheered them both up. However Alvin's good mood was completely ruined. "Thanks a lot you two" he mumbles before heading to his shared room.

3 days later...

The chipmunks and the chipettes were getting ready to go to the prom. Simon who was wearing dark blue tuxedo with a black bow tie, was in his shared room helping Theodore putting on his tie. Theodore was also wearing a tuxedo. His was dark green with a light green tie and red rose on its side. Alvin, who was in the bathroom putting in hair gail, he was wearing a dark red tuxedo with a pink tie and he was the only one who planned on using hair Gail.

Meanwhile with the girls, Jeanette was in her room looking for her favorite hair and she was wearing a purple one shoulder dress and was wearing makeup and she planned to not take her glasses with her. Eleanor who was in the living room speaking with Dave, was wearing a green pouf dress and was also wearing makeup. Brittany was in the bathroom brushing her hair, was wearing a pink sun dress and a red rose attached by her pony tail.

"EVERYONE PLEASE LITEN UP, WE HAVE TO GO NOW OR YOU ALL WILL BE LATE FOR THE PROM" Dave shouted from downstairs. Soon everyone for downstairs and the boys were stunned by the girls looks. "Hey Britt, you look hot" said Alvin which makes her giggle. "Thanks Alvie, you look great to" replied Brittany before kissing him on the cheek. Simon approaches Jeanette and says "uh hey Jean um you look gorgeous" Jeanette reddens before wrapping her right arm his left arm. Theodore was to speechless to say anything. Eleanor knew that he was impressed by her look and says "I can tell that you think I look beautiful huh Theo" the chubby chipmunks before holding hands with her.

They got to Dave's car and made their way to the school. By the way, Dave had told the teachers the good news about Brittany not being dead. Dave had to make up a story about Brittany still being alive and was mistaken for being dead therefore, she was buried alive however, he said that heard screams every night so, he went to the backyard to hear the screaming coming from her grave. Dave told them that he had a weird feeling so, he said he dug and took out the casket and opened to see Brittany alive and well. The whole world was shocked by this, a lot of their fans believed the story but some didn't. Some thought that Brittany was a zombie and others thought that it was clone of her.

Tonight was the first time Brittany went to school in her own body in about 12 days. Now she was going to get to see her teachers and her best friend Laura again.

The chipmunks got to the school and they made their way to the gym were everyone was. When they got there, they were almost runned over by students hugging and asking Brittany questions which took a while for her to get rid of them. "BRITTANY" she hears her name and turns around to see her best friend Laura running to her. They hug each other and she says "Oh Brittany I thought I would never see you again. how are you girl?" she question as she looks at her Brittany's dress.

Brittany gladly tells her "oh I'm good and I missed you to bestie" Laura giggles and was about to say something if the dj hadn't talked first. "ALRIGHT, HOW IS EVERYONE DOING TONIGHT? the crowd roars with cheers. "I SEE A LOT OF HAPPY FACES AND I CAN TELL THAT YOU ALL WANT TO START DANCING WITH THAT SPECIAL SOEMONE" the crowd cheers again. "ANYWAY, THE REASON WHY WE ARE HERE AND THE REASON WHY THIS PROM WAS MADE WAS TO CELEBRATE BRITTANY SEVILLE'S RETURN TO SCHOOL AND A NORMAL LIFE... LETS GIVE IT UP FOR BRITANYYYY" the crowd begins to cheer and chant Brittany's name. "ALRIGHT EVERYONE, IT'S TIME TO DANCE" the gym gets mostly dark and the only light shining was the giant disco hanging from the ceiling.

Brittany grabs Alvin's paw and makes her way to the middle of the crowd. Alvin wraps his arms around her waste as she does the same with his neck.

Simon who gathered all the courage approaches Jeanette. "May I have this dance my lady?" he questions. Jeanette winks at him and accepts.

Theodore who was eating a chocolate bar, approaches Eleanor and questions her "um Ellie do you want to um you know... "Yes Theodore" She happily replied before taking his paw. They start to dance as well.

2 years later...

"Alvin, do you take Brittany as your wife, that you'll love and respect until death separates y'all?" questions the preacher. "HECK YEAH" yelled Alvin and which makes some of the everyone laugh except for Dave who gave him a disapproving look. The preacher also found it amusing and then questions the bride. "and Brittany, do you take as your husband that you will love and respect until death separates y'all?" Brittany glances at Alvin and says "I do" Alvin puts the ring in her finger and she does the same with his. "Very well then, you both are now husband and wife" he looks at Alvin and says "you may kiss the bride" Alvin looks at Brittany's blue eyes and slowly kisser her.

They then begin to walk back however, Alvin tripped on the wire for the microphone the preacher was holding making him hurt his knee. "OOOH SHIIII-""ALVINNN" shouted Dave and everyone everyone begins to laugh.

The end
