Dave was back in the dinning room and takes a seat as he had a worried look. Simon who was spoon feeding his girlfriend Jeanette asked, "hey Dave is everything alright?" and his father looks at him. "No, I'm starting to worry more about Alvin, because a minute ago I caught him wearing a pink sweater instead of his usual red on and also, he was talking to himself, he was pretending like he was talking to Brittany and I know this because I heard him say her nick name" Dave informed them which brings sad memories back. Both Eleanor and Jeanette began to sob on their boyfriends torso. "Um Dave, i think Alvin should see a psychiatrist because he seems to be getting worse" Simon advised as he rubbed his girlfriends back.

Dave who had a few tears as well says "you're right Simon but, first I'm going to have a talk with Alvin after dinner" Simon nods and then glances at his younger brother who was trying to hold his tears. Simon puts an arm on his shoulder and says "it's okay to let it out" Theodore looks at him but doesn't say anything as his eyes get watery.

Suddenly they heard footsteps and see someone familiar approaching.

As soon as Alvin went in the dining room, all eyes were on him. He takes a seat and looks at his food before looking up to see the his brothers and the two girls staring at him. "What?" he questions them and Simon replies "Alvin, why are you wearing that? You know that it only brings painful memories and you know that we're trying to move on" this infuriates Alvin who smashes his plate on the floor. "Don't you ever tell me to move on dear brother, because Brittany will always be here with us and will never be forgotten" Alvin told his brother. Now there was silence as the sadness grew. Alvin storms to his room and they all hear him close the door loudly.

Dave couldn't hold it anymore and begins to cry which breaks Theodore's heart. The short, chubby chipmunk approaches Dave and hugs him tightly. Next Simon hugs him to and then the two girls join the hug.

In the meantime, Alvin was in his room trashing everything of his belongings as Brittany tries to calm him down. "Alvin, baby chill" Eventually, Alvin who was breathing hard, sits on his bed rubs his temples. "Britt, I can't calm down not after what that nerd said" Alvin responded. Brittany's spirit leaves Alvin's body and sits next to him. "Alvin look at me" she demands before placing her paw on his. Alvin turns to look at her and realizes something. "Wait, I'm actually able to see you without a mirror?" He questions as he looks in to her icy blue eyes. "Yeah, but only you're able to see me like, if I appear in front of others they won't see me for some reason" Brittany responded. Alvin looked at her even confused and asked "how do you know that?" Brittany kisses his cheek before saying "because I was standing next to you when we were downstairs and Dave, my sisters and your brothers were staring at you. I noticed that they couldn't see me" Alvin then tells her "oh I see and by the way, I think it's time for them to know that you're still here" Brittany gave him a confused look and asked "unfortunately that can't happen because they can't see-" Alvin cuts her off "I know that but, there's still a way that they can know that you're here" Brittany stays quiet as she thinks.

"Then what is it?" She asked. Alvin looks at her paws on him but, he can't feel her touching him and says "Simon has this kind of machine that can detect if you're lying or telling the truth so, my plan is that we switch like we did in school, and you'll ask Simon to test his machine with you by asking you questions that way I would have proof that shows you're still here" Brittany smiles at his plan and says "that's sound great but, are you sure it's going to work?" Alvin tries to kiss her but his face goes through hers which embarrasses him a bit. "Sorry, and I'm sure-" he stopped talking when he saw the door open.

Dave came in worried and questions him "Alvin, we need to talk?" Alvin hops off his top bed and sits on Theodore's next to Dave. "Listen, I have been thinking about this for a day now and I have decided to take you to a psychiatrist" Alvin dislikes what he heard and gets up "oh I see, you think I'm crazy? Is that it?" Dave puts hand on his head but, Alvin shoves it away. "It's not that, it's just you've been-" "no you listen to me Dave, if I can prove to you that I'm not losing my mind, would you forget about taking me there?" Dave looks at Alvin stunned and says "what, what do you mean by prove to me?" Alvin sighs and says "Brittany never left" Dave looks at him sympathetically before saying "Alvin, I know it's hard to let go of the past-" "You don't get it, she's still here... with me" Dave gets hugs his son and says "shhh, she's gone Alvin, and we only have memories-" "Alright, fine don't believe me but, I'll show you that she still here" Alvin stands on the floor and closing his eyes.

"Brittany, let's do this" he says and she responds "okay, here I go" in a few seconds Alvin began to lose control of his body as Brittany gained control. Meanwhile, Dave watched Alvin's strange behavior. He saw his son shaking and a he feels a breeze coming from him which creeped him out. "There, you can do it Britt" Said Alvin in her mind. Brittany glances at Dave and says "Dave, how you been?" she jumps to hug him but Dave doesn't hug her back. He was still trying to figure out what just happened. "Alvin, I don't know how you managed to do that but, now I'm more convinced that you need to see a psychiatrist" Brittany stops hugging him before saying "Dave it's me Br-" "Alvin I know it's hard but, you have to accept that she's gone okay" Dave told her and then kisses his forehead. "I'll see if you can have an appointment this week okay, now go brush your teeth because it's almost bed time" Dave heads out of the room to the living room.

Brittany stares at the window and was thinking. "I knew this I plan wouldn't work and-" "What do you mean? you haven't even tried, now go get Simon and ask him if you can use his machine" Alvin who read her mind, interrupted her. "Alright, alright" Brittany heads out the room to the living room. She gets there and sees everyone watching meerkat manor. "Simon?" Everyone turns to look at her. "What is it Alvin?" He questions as he had an arm around Jeanette's shoulders. "Could I use you're lie detector machine?" She question and earns curious looks from everyone. "What do you need it for?" He questions. "You'll know why and I need all of you to come with me right now" Brittany replied. Everyone looks at each other before Simon walks to the basement as the others followed.

Simon approaches a chair with a computer mouse on a table next to the chair. "Sit here and place your paw in the mouse" Simon tells her as he turns on the computer and she does. Next he wraps some wires on her fingers. "Now what kind of questions do you want me to ask you?" Simon asked and Brittany thinks for a minute. "before I tell you, I want you all to know something, I'm not really Alvin. I'm Brittany using Alvin's body, and I'm actually still alive but I don't have my body so, Alvin is letting me use his so I can communicate with you all to tell y'all that, I never left and I was in this body the whole time. Also the reason why my spirit never left this world is because, when I fused with Alvin, my spirit was I guess attached to his so, it's like it wouldn't leave unless Alvin's spirit came along so, that's the reason why I'm still here using Alvin's body with his permission to tell y'all that" unfortunately for her, none of them believed what she said.

"Uh huh, fascinating, now please tell me the first question that you want me to ask you Alvin" Simon said as he started to lose his patience. Brittany was expecting this kind of reaction from them and says "alright then, ask me if I'm really Brittany" Simon shakes his head and says "Alvin stop wasting my time, and ask me something else something that can be true" Brittany starts to become frustrated and says "I told you, ask me if I'm really Brittany" Simon sighs before asking "are you really Brittany" "YES" she answered quickly.

In a few seconds, Simon got the result to the first question. "What the?" the results showed that she was telling the truth. The others look at the computer screen and started to look from the screen to Brittany back and fourth. "Uh okay I'll ask you the next this time, who-" Simon was interrupted by Eleanor. "What did Brittany get me for my birthday last year?" Brittany easily remembers and says "I got you a blender and a hair dryer" which stuns Eleanor and Jeanette. Simon got the results and she was correct. Everyone looked at Brittany wondering if it was actually her because Alvin didn't know what Brittany got Eleanor for her birthday last year since he didn't attend her party because he was grounded for a month for breaking one of the windows of his school with rock. "Let me ask you a question, what did you told Jeanette and I about what you thought of Alvin the first time as soon as you saw him on tv?" Jeanette questions which is a question that only the chipettes know the answer to. "I thought he was a cocky, selfish, player who plays with every girls feelings that came to his life" now Jeanette and Eleanor were shocked even more because those were the exact words that Brittany said a couple of years ago.

Simon got the results and she was telling the truth. Everyone gasped before looking at their sibling that they thought was gone forever. "Big sister, is it really you?" Questioned Eleanor as tears were coming out. "Yes Ellie, it's me Brittany" she replied. Eleanor jumps to hug her sister so tight as she let her tears fall. Second Jeanette joins the hug and then the rest. "Britt, sniff, I thought that, sniff, we would never see you again sniff" Eleanor said as she kept hugging her. "We missed you so much" Said Jeanette. "We missed you to" said Simon and Theodore together.

Meanwhile Brittany couldn't breath so she tells them, "um guys could y'all back away a little, I can't breath" everyone chuckles before getting off her. Brittany's catches her breath before noticing Dave standing far away as tears were rolling down his cheeks. "Dave?" She calls him. Dave comes turning to her and hugs her with so much love. "Brittany my baby, I'm so happy to know you haven't left us" Dave said before sniffing. "I missed you to Dad" replied Brittany which felt good calling him that. "This means that Alvin was telling the truth the whole time and I didn't believe him" said Dave before slapping his own forehead. "Dave please don't be hard on your self, it's understandable to why you didn't believe him" Brittany responded. Dave let's her go and says "still, I can't stop feeling guilty though. He told me when I was in his room that you were still with us but, I wasn't listening and kept telling him that he needed to see a psychiatrist" Brittany cleans Dave's tears and says "but now you know that I'm really here and that's all that matters" Dave's sniffs a one more time and says "you're right" he then stops hugging her and puts her down.

Now there was awkward silence between them. suddenly Simon speaks "so, does this mean that you'll still be with us forever?" Brittany gladly nods before saying "yep however, since I don't have my body anymore, I'm going to have to live inside Alvin since his spirit is part of mines and he doesn't mind sharing this body with me" everyone looks at her amazed and sad. "Oh I wish we could get to see you again in your original body" said Eleanor before grabbing Brittany's new paw. "Me to but it's better that I'm actually here than-" "WAIT" Simon startled them before saying "I don't know how I'm going to do it but, I will restore your original body Brittany, I promise you that. By the way, I'll need your help Jeanette" this leaves everyone speechless for a few seconds. Jeanette kisses his cheek and says "that's one of the reasons why I love you. You love to help others when they desperately need a hand" Everyone looks at the couple in awww. "Well I'll get started now" Simon said before leaving with Jeanette.

Everyone gives their attention back to Brittany. "So Britt, what do you feel as your using Alvin's body?" Eleanor questions as she looks at Brittany up and down. "Um i feel a bit strange, for example I'm a little taller and I can tell that Alvin works out because these arms are somewhat muscular" Brittany replies as she looked at her new paws. All of a sudden Eleanor comes up with an awkward question. "Um what about the rest, like does it feel the same down there?" Brittany blushes because she knew what Eleanor was trying to asking. "Oh that, yeah it feels different but, I'm not planning on looking at it until Alvin and I are married.. Well that's if I get my body back" Brittany responded. Eleanor begins to giggle at her face and so does Theodore. "Wait, what are you going to do when you need to do your business in the bathroom or take a shower?" Brittany starts to feel weird with Eleanor's questions. "Um if ever need to use the bathroom to shower or whatever, I'll switch with Alvin, so he deal with that since it's his body" Brittany replies. "Oh okay but what abou-" "So guys, now that you all know I'm still here, what do y'all want to do?" Brittany changed the subject avoiding even more of Eleanor's awkward questions.

Dave happily says "well, right now I'm going to call Dr. Rubin to ask her if it's okay if the school can have a prom for all grade levels and I'll pay for everything and I'm going to do this for you Brittany, to celebrate that you're still with us. Also, I'm not going to tell her that you're still alive because she might think I'm crazy but, if Simon manages to restore your body then I will tell her the world the good news" Dave managed to put smiles on all of their faces making them jump on him to hug him.

"That would mean so much to me dad, or Dave wait you know what? I'll call you dad instead because you deserve for me to call you that since you've been there for all of us with love" said Brittany as she played with Dave's hair. Dave gently grabs her and holds her. "Um Brittany, does Alvin know the good news?" Dave questions. "Oh snap I totally forgot about him" she closes her eyes. "Alvin, are you there?" "Alvin hello are-" "yeah I'm here and I heard the great news, I also heard what Simon and Jeanette are planning to do. Dang that Simon sure does give me surprises, sometimes he can be a pain in the neck but others times he's the best brother in the world" Alvin responded in her mind. "Yep, oh do you want to take control of your body?" She questions. "No that's okay, you can keep using it until you feel like you feel like you need to use the bathroom or something" Alvin responded in her mind.

"Oh okay, thanks baby" Brittany replied before opening her eyes. "Yeah he knows, anyway I'm going to check what Simon and Jeanette are doing" Brittany makes her way out of the basement.
