A/N: Optimus and Harmony spend a little time together. You all know disclaimers. Next chapter? Prowl and Harmony have some father and daughter bonding. BTW, this chapter will be REALLY short.

Family is Forever – Chapter 7 – Precious

Harmony warbled inquisitively, touching the circle shaped block and twittering excitedly as it changed colour from red to yellow. She did the same to another, and clapped her hands together as it let out a low hum, rather than changing colours. Tilting her helm to the side, she then went for a rectangular one and touched it. Nothing happened. She beeped and clicked at it, before reaching for it and stacking on top of two other blocks.

Optimus Prime, leader of the Autobots, chuckled as he watched the little white sparkling play at the side of his desk, her little winglet nubs swaying happily.

The semi was happily watching his 'niece' as Prowl and Jazz got some rest and attended to their duties. They had protested, saying they were imposing, but Optimus insisted that it was a joy and an honour to look after the little femmeling. Besides, he had wanted the chance to watch her. He had not seen a sparkling for so long, and had wanted to see the innocence, the simpleness of need that sparklings possessed. It was such a refreshing change from everyday life and gave him the hope to see the end of this war…to maybe have a sparkling of his own with Elita.

A series of hums filled the room, going from low to high pitch as Harmony gathered all the music playing blocks around her. She giggled and warbled, looking up at the large mech and offering him a block.

Smiling behind his mask, he rumbled softly, "Thank you, Harmony."

Her winglets flapped and she cooed, going back to the other blocks.

Placing the humming triangle block on his desk, Optimus reminded himself to thank Wheeljack for making the set of blocks. They really were quite creative. They were made of all different shapes of mostly the same size, and there were three types: the humming blocks, normal blocks, and the blocks that changed colours whenever they were touched.

Ignoring his datapads in favour of watching Harmony, Optimus felt a protective urge settle over him.

Harmony was so precious.

She was a true gift to those on the Ark, and true gift to their creators. In fact, since they had bonded, Optimus had not recalled a time where their duties were carried out more efficiently, Prowl and Jazz working together in such a way that their plans were given more than 90% chance of success each time – and morale was at an all-time high…all because of the little bundle of wires sitting before him. And he knew that he would do anything to keep her safe from any harm, same as Prowl or Jazz would.

A few little clicks prompted the red and blue mech to look down again.

Harmony was rubbing her optics with one hand, the other reaching up for him.

Optimus chuckled. Prowl did say that she would need to recharge within the time she would be there. With large, gentle hands, he picked the little sparkling up, settling her on his forearm so she could curl into his chest. She instinctively trusted him, she had since the first time he laid optics on her. Maybe it was because he was a Prime. But apart from her creators (and Sunstreaker, much to his chagrin), Optimus was the only mech she was truly comfortable being with.

"Recharge, little one," cooed Optimus, stroking a finger over the nearest sensory horn.

With a little squeak, she shuttered her optics contentedly and did so.

An affectionate smile on his face, he whispered, "Sweet dreams, little precious."
