Jazz carefully carried the wide eyed little girl, now dressed is her new clothing and wearing her new glasses, as they wandered around the base. S4 would point at different things, and Jazz would explain them to her. And with each and every new discovery, S4 was enjoying herself more and more and finding that things seemed less and less scary. And while Jazz and S4 were walking around, they ran into Ironhide, whose attitude seemed to scare S4, and she tried to hide in Jazz's hand.

"Nice job, 'hide, you managed to scare her" Jazz snapped at Ironhide, as Jazz was taking this caretaking business seriously.

"Wasn't tryin' ta, I'm just in a hurry" retorted Ironhide, who stomped off before S4 would peep her head out again.

"Sorry about that, S4, Ironhide has a tendency to be a bit gruff, but he has a good spark" Jazz told S4 who looked up at him with her precious blue eyes full of curiosity and worry, "and don't worry, most of the rest won't be as grumpy as him either" and with that Jazz tickled S4 until she giggled hard and forgot about gruff old 'hide.

And as the two rounded another corner, they bumped into what S4 thought was the biggest thing she had ever seen. S4 was scared, but with some coaching and soothing from Jazz, S4 poked her head back out and met Skyfire. Skyfire was much gentler than Ironhide and soon S4 was giggling and laughing as Skyfire began to talk. But when Skyfire had to go, S4 left Jazz's hand to give Skyfire a big hug. Jazz was surprised, as was Skyfire, but Skyfire carefully placed the little girl back with Jazz and then headed off. S4 was smiling and Jazz felt proud, as if this was his new sparkling that had just been sparked and it was his job to teach her all the tricks. And so Jazz and S4 continued on, though the bot that S4 was looking most to seeing was nowhere to be found at the moment.

Jazz and S4 entered the rec room, and met up with many different bots, including Ratchet who was on break, Wheeljack who made S4 laugh with all his stories of being blown to pieces, the Lambo twins, who S4 really didn't care for, Bumblebee who S4 loved, as well as Bluestreak, who S4 did not know yet was now her big brother but loved nonetheless. Soon, seeing that S4 was getting overwhelmed, Jazz took S4 to Prowl's office, passing Optimus's office along the way.

Upon seeing the bright red and blue bot, S4 banged on Jazz's chassis to let him know that she wanted to meet the big red and blue semi. Jazz, seeing how eager S4 was, took the little girl in to meet the commander of the Autobots. Optimus, upon hearing the interruption, looked up from his desk and his work to see Jazz holding little S4 in his hand. Optimus smiled as Jazz set S4 down on Optimus's desk. S4 was surprised by just how big the commander was, but she knew she needn't fear him.

Optimus scanned the internet with his processor and started speaking in rudimentary sign language with S4, while he talked. S4, always eager to learn, started signing back even though she could hear just fine and write somewhat well. Optimus smiled and recommended to Jazz and Prowl that they teach S4 sign language so it would be easier for her to communicate her needs. Both Jazz and S4 smiled as they left, and just before they left, little S4 signed "thank you" and then disappeared. Optimus laughed, as the little girl was certainly a morale booster during this trying time, and soon the commander was back at work.

Jazz then carried S4 into Prowl's office and found the tactician locked up and frozen at the desk. Jazz looked down and saw that Prowl had been reading a report from Red Alert and had frozen up. But soon, Prowl was rebooting and went back to work, not realizing that S4 and Jazz were already in his office. But when Jazz cleared his throat, Prowl flipped out, not expecting in his office and both Jazz and S4 laughed. This is the bot that S4 had been looking for and had not seen, as S4 did not know just how much work her guardian did around the base. Prowl recomposed himself quickly and chided Jazz, while taking S4 and holding her quickly close to his spark and then handing her back to Jazz, which was the way Prowl had learned to hug the little one.

Prowl was caught slightly off guard when little S4 began signing at him, but after running a scan on the internet, Prowl easy began to figure out what little S4 was doing, she was trying to use the human sign language. Jazz told Prowl that Optimus had first brought it up and since then, S4 had been enthusiastic in learning the new form of communication. Prowl agreed that it would be easy to teach her multiple forms so that she would be able to communicate several ways. And since Prowl had finally finished his work, Prowl and Jazz headed back to their shared quarters to teach S4 how to read, write, and sign.

But there was a surprise waiting for all three, and as Prowl and Jazz entered the quarters, Bluestreak was sitting on the couch watching the large screen in front of him. S4 was confused, and was pointing at the bot and then using her body to ask why the other bot was here. Prowl, a little more attuned to S4's body language, soon answered her question.

"S4, this is Bluestreak. He is our son, though he his much older than you. He is your brother, dear" stated Prowl, finally getting a hold of Bluestreak's attention.

"may I hold her?" asked Bluestreak to Prowl and Jazz, who looked at S4 to see if she wanted to go to Bluestreak.

If S4 could have squeaked with pure pleasure, she would have as she raced from Prowl's hands into Bluestreak's and gave the big bot a hug, her love so bright in her eyes. Bluestreak as well as Prowl and Jazz smiled as they realized just how much little S4 added to their little family. And since S4 was content to be with Bluestreak, Prowl and Jazz decided to spend some alone time together.

Prowl and Jazz sensuously began to enjoy each other in their bedroom, which was far from where Bluestreak and S4 were watching the big screen. And as the two warmed up, the removed their plating and began giving each other pleasure. And as they brought their sparks out to reaffirm their bond, neither noticed the flash of color change when the two bonded. And the two rested for a short time, unaware that Jazz was yet again expecting, before going on and joining Bluestreak and S4 in watching the movie on the large screen. S4 curled up on Prowl's shoulder that was closest to Bluestreak and fell asleep during the movie. The three large bots smiled, as S4 was just too precious.
