Jack is twenty years old and has found out that Arcee is twenty as well and that Cybertronians age slower.
Also the effects of a relationship between a human and an autobot are unknown to the characters in this story.
It was a normal sunny day in Jasper, Nevada and Arcee was waiting in vehicle form outside KO Burger for Jack to get off work. When Jack stepped out of the fast food restaurant he walked over to Arcee and said
"How was the mission to secure that Energon Mine?"
"A success, as usual" Arcee replied "So some more target practice in the desert" Jack said as he knelt down and kissed the top of her headlights
"Actually I thought of something else" Arcee said in a seductive tone and Jack climbed onto her seat and they sped off to Jacks home.
…
The Garage of the Darby home had tools hanging on every wall as well as gardening tools sitting on the floor below them, Jack hopped off Arcee and she said
"Well Jack I got Ratchet to help me change my transformation slightly to accommodate a third form" Arcee then transformed into this form and when she had completed her transformation Jack's eyes widened, he no longer saw the Arcee he knew instead he saw a woman the same height as him with long black hair that had a pink highlight on her left side standing in front of him and then he realised then she was unclothed and he ran an grabbed a bathrobe to cover her.
When she was covered Jack said with surprise in his voice
"Wow, you still, look beautiful Arcee. Wait did you tell Ratchet why?"
"No Jack he just thinks it's for stealth purposes" Arcee assured him
"Well Arcee since you are no longer too tall for the house we don't need to stay in the garage" Jack added as he took her hand. They both walked through the door and sat facing each other on the couch in the living room.
"Arcee what made you want to do this?"
"Well I saw the way Miko is with her boyfriend, walking together, holding hands, kissing and I realised we can't do any of these things at least not in public" Arcee placed her right hand on Jacks neck and pulled him to her, they closed their eyes and parted their lips slightly just as the door to the garage opened quickly and June Darby came walking in and when she saw Jack she said
"Hey, is Arcee with the Autobots?" then she saw human Arcee and said "I mean is your bike still in the auto repairs shop?"
"No I'm not in either of those places" Arcee chuckled covering her mouth with her hand
"Wait, Arcee? Are you wearing my robe, why are you wearing my robe?" June sounded surprised
"Well Jack got me it to wear when I told him about this third form Ratchet helped me with… for stealth purposes in case we go up against M.E.C.H again" Arcee explained and June appeared to understand
"M.E.C.H? What's that?"
"It's a human organisation that wants to use cybertronians to create weapons" Arcee casually explained
"Well Arcee come here with me" June took Arcee up the stairs to her room while Jack waited patiently for their return, June was the first to come back down and Jacks eyes widened when he saw Arcee walk down the stairs, she was wearing a long blue sundress, blue high-heeled shoes and she now also wore thin oval glasses that rested on her freckled nose in front of her bright blue and pink eyes, Jack's jaw dropped as he saw her walk down the stairs
"C… Cee you look amazing and… um also human" Jack said nervously when Arcee walked over to Jack, June said "Well Arcee you look much better wearing that than, MY robe"
"Well June I think I'll use the human name Sadie for this form" Arcee said
"Ok so when did you two start dating?" June asked they both began to look nervous and together they said
"Dating? We're not dating… what would make you think we're dating?"
"Come on, Jack I'm your mother I can tell when you're trying to lie to me and Arcee I see the way the two of you look at each other, that's not a secret crush look, that's the boyfriend/girlfriend look"
"Wow, you're very observant" Arcee said with a surprised tone
"It comes with being a parent"
"Ok we should probably go check in with Optimus" Jack said
"I'll drive you there" June told them
"Yeah it'll be nice to be driven somewhere instead of being the one driving"
…
When they got back to the Autobot Outpost Omega Two that was hidden in a mountain June stopped the car and all three of them got out, Arcee immediately walked over to Ratchet and asked him to help her while Miko came over to Jack and said
"Hey what gives bringing someone else in here and where's Arcee anyway?"
"She's out on patrol" Jack lied
"Ok, what's this new girls name anyway?"
"Sadie" June told her
"Hey Miko how are you and your boyfriend?" Jack asked
"I broke up with him, he said I had bad taste in music"
"Hey Miko" Arcee chimed in casually as she walked back over
"Wow, how do you know my name?" Miko asked "No reason, except I'm Arcee" both Jack and Arcee let out a chuckle while Miko glared at them then Arcee placed a hand on Jack's right shoulder and whispered in his ear
"Follow me honey" Jack nodded and followed her, as they walked Jack stared at the curves of her body swaying gently, as they walked down the hallway Jack asked
"Hey Cee do you know what Sparkmates means?" Arcee stopped and turned to him a confused look on her face "Why are you asking about that?" "Well because I read about it when I looked through some of the books Ratchet keeps about Cybertron" Jack explained rubbing the back of his neck
"Jack Sparkmates are bound together forever. Why? Do you want that?" Arcee asked as she stepped closer "Cee I love you, and yes I would" Arcee then turned and continued walked with a smile
They both walked into Arcee's quarters and Jack immediately saw a human sized bed against the wall opposite her own, Jack walked over to it, turned and asked "Cee why is this bed in here?" "Well Jack I wanted to act more human so…" Arcee gestured towards the bed then Jack cupped Arcee's cheeks in his hands as she slid her hands around his neck and pulled him towards her, they closed their eyes and parted their lips slightly, Jack then ran his left hand down Arcee's neck and along the curve of her body then they pulled apart slowly Arcee smiled seductively, removed her glasses and shoes and slid her arms out of the dress and let it fall to the floor, Jack now stared at Arcee who was now only wearing her black underwear she then moved back to Jack who put his arms around her as their lips met once again, Jack then removed his shirt and Arcee pushed him down onto the bed and climbed on with him as their lips met once again Jack ran his hands along the curves of her body starting from her chest while she ran her hands over his chest, Jack caressed her metallic skin. Arcee's spark and Jacks heart began working together and Jacks eyes began glowing blue.
…
"Has anyone seen Arcee and Jack?" Optimus asked standing in front of the groundbridge
"Yeah I just saw Jack heading into Arcee's quarters" Bulkhead said as he walked into the main room then Optimus began walking to Arcee's quarters
…
Arcee let out a soft moan as she playfully bit Jacks lip, to both of them nothing else was there not even the bed they were on, it was just them until they heard the door open and they both looked up to see Optimus walking in his eyes widened when he saw them
"Oh scrap" they both exclaimed and he said "Arcee, Jack, command center now" as he walked out Jack Grabbed his shirt and watched Arcee slip her dress back on followed by her shoes and then when she put her glasses back on she transformed back into her robot form and they both walked out and followed Optimus back in silence when they reached the main room everyone looked round and Optimus then said
"Would you two like to explain" "Optimus it's just I love Jack and he loves me, we're Sparkmates" Arcee explained
"Arcee did you to think about this first I mean did you explain what a Sparkmate is?" Ratchet asked looking concerned Miko then walked over and asked
"Hey what are Sparkmates?" "Miko it's when two sparks merge but Jack is human he doesn't have a spark, he has a human heart" Ratchet explained "Hey Jack why are your eyes glowing" Miko asked "What?" everyone called out as Jack looked at his reflection in Arcee's leg, then Ratchet knelt down to look
"By the Allspark. You two actually managed it. You managed to merge a heart and a spark"
"What does that mean?" June asked stepping forward "June it means that they truly do love one another" Optimus told her then Smokescreen and Bumblebee can driving in with Rafael as Arcee transformed into her vehicle form and said "Hey Jack do you want to get out of here?" "Cee, you read my mind" Jack said with a chuckle then he climb onto her seat and they sped off out of the base
"Hey Cee, I heard about a new movie, it's supposed to be romantic, wanna go see it?"
"Sure Jack that sounds good" Arcee replied
It took them about half an hour to reach the movie theatre that was part of the new Mall in the now rebuilt town of Jasper. Arcee stopped in the parking lot and Jack climbed off and checked to make sure the parking lot was clear of people before saying
"Ok Cee the coast is clear". Arcee took that as her cue to change into her Sadie form and took Jacks hand and they both began walking in. As they neared the entrance, Arcee gave a smile when she saw a young girl about four years old come running past her laughing while her mother chased her yelling "I'm gonna get ya, I'm gonna get ya" with her arms outstretched also laughing and when she caught her she picked her up and spun round hugging her close then Arcee looked at Jack who also smiled at the sight as he slid her arm around her but then he stopped and asked
"Cee does your human form have weapons because if it makes you defenceless…"
"Jack its ok this form uses smaller versions of my blasters, speaking of which" Arcee's wrist opened and she pulled out what looked like an ordinary glove but when she turned it over it had the Autobot symbol on the back, Jack put it on and Arcee explained
"It's thought controlled it looks like an ordinary human glove but for defence it changes into a blaster similar to my own, Ratchet designed it" Jack concentrated on the glove and he watched it transform into a blaster like Arcee's "Its light, I don't even feel like there's anything except a glove on my hand"
"So you like" Arcee asked with a coy smile "Oh yes I like, now I can help you out on missions" Jack replied "What makes you think I'd need help?" Arcee said still smiling "What makes you think you wouldn't" Jack asked smiling with her, they both resumed walking. Arcee sat with Jacks arm around her as they watched the movie with the occasional glance over at him.
As they walked out of the theatre Arcee said with a chuckle "Well I know I've had the time of my life" then Jack and Arcee walked past a women's clothing store and Jack said
"Hey Cee why don't we have a look in here because well you are wearing my mom's clothes"
"Well it would be better to have other clothing options" Arcee agreed then they both strolled inside emerging half an hour later both carrying a bag of clothes they walked out of the mall and down a nearby alleyway where Arcee radioed Ratchet for a groundbridge, a minute later a groundbridge burst into life beside them and closed after Jack and Arcee walked through.
The others had returned to whatever they were doing and Jack took the second bag from Arcee as she walked towards the platform and he took the bags to her quarters while she climbed the ladder, Raf and Miko were playing a racing game while Bumblebee and Bulkhead both watched. Both Raf and Miko looked over at her when she sat down on the couch beside them "It's kinda surprising seeing you at human height" Miko said casually as they resumed the game. As Arcee sat back in the couch and felt hands cover her eyes and then a voice saying
"Guess who" "Hmm, Agent Fowler" Arcee giggled Miko looked up at her, eyes widened "Arcee did you just giggle?" Jack took his hands away, walked round to the side of the couch leaned against it and kissed her.
Miko made a gagging noise as they kissed until Ratchet said
"Jack come over here for a minute" Jack did as he was asked and Ratchet set some clothes down beside him and said
"Put these on" as he did he noticed that they had a slight metallic feel and once he had them on Ratchet explained "I assume Arcee has given you the weapon I designed" Jack replied with his glove transforming into the blaster "Ok good well these clothes work the same way they will change into armour that will protect you from most types of damage as well as improve your agility and speed, I also added a second blaster to the other hand as well" Jack then felt the clothes encase him in armour with the helmet clicking into place then he did a back flip and landed on the platform beside Arcee "Wow thanks Ratchet" Jack exclaimed as the suit changed back into a t-shirt and jeans and the helmet seemed to change into a set of dog tags.
Then an alarm at Ratchet's console alerted the room and Ratchet said
"There's a faint energon signal on the other side of Jasper" "Energon has been unearthed here" Arcee said in disbelief "No! It appears that there's a cybertronian in trouble" "We need to help them" Jack yelled "Indeed, Arcee you and I will aid them" Optimus said walking into the room "I'm going too" Jack said as his suit changed again "Jack it may be too dangerous"
"Optimus I'm going, anyway there's strength in numbers" Jack told him and reluctantly he agreed
