Bulma waited as the computer whirred and beeped it's way through the program she'd written for it. She yawned hugely and reached for the printout. Highlighting several strings of data, she smirked. She'd worked on this non-stop longer than any other project before, but the Genius Bulma had done it again. No way he'd blow this one up… for a little while, at least. One or two manual tweaks to the system, and it would be done. She picked up a couple of tools she'd specially designed herself and tiredly, but triumphantly, walked out the door.
…
Like a Sayijin, the new Gravity Chamber had sprung up from the rubble fortified, Vegeta reflected. He inspected the new building in the pre-dawn light, warming up as he did so. Then he marched in, looking for work crews, or unfinished pieces, to yell about. If he was going to beat the Androids, the place had better be ready for him to start training immediately.
What he found was a grubby, blue haired, human female. She was fast asleep, hugging her tools, on the floor. He stared at her for a moment, his eyebrow raised in curious surprise. Even on Namekia she had been dressed up. She had always worn clean, matching clothes, done odd things to her hair, and added enticing smells to her own scent.
This female, sleeping the sleep of the dead, looked like she hadn't bathed or slept in weeks. And she wasn't even awake for him to smirk at. So he frowned thoughtfully, and carefully picked her up.
She mumbled something and snuggled into him, causing him to freeze. Both eyebrows raised, he regarded his bundle. She looked like any warrior, sleeping off exhaustion after being pushed to the limit. No one was there to see his slight smile as he flew her to her balcony.
He simply blasted the lock, kicked the door open, and went inside. Immediately, he was assaulted by traces of her perfume mixed with her unique scent. The room was also full of bright colors that were a shock from the colorless life he had lived. He froze, and then relaxed. So many things were different here, he pondered as he laid the silly woman on her big bed.
Without waking, she lazily protested the loss of warmth. He smirked, and then covered her with the comforter from the end of her bed. He paused a moment longer than necessary to study her, as if she contained the answers he sought. Then he was out the door, as if he had never been in the bright room.
…
She woke slowly, luxuriating in the softness of her bed. Upon becoming fully awake, she was displeased, as well as confused, to find that she was very dirty, fully dressed, and sleeping with grubby tools.
Then she remembered her 'mission' to fix the Gravity Chamber. She sat up triumphantly as she remembered splicing the very last wire.
Bulma got out of bed, grimacing at the work boots she still wore. Kicking off the boots, She headed for her bathtub, shedding clothing as she went. She giggled at herself; she must have been extremely tired; she didn't even remember the walk back to her room!
…
Vegeta trained.
…
Bulma was fully awake when she returned to her room, having enjoyed a long and cleansing bath. She was happily pondering what she would wear for her victory breakfast, when she noticed the balcony door was ajar. She shut it, only to have it swing partially open again almost immediately. Frowning, she examined the door, to find most of the bolt melted to the door, and the rest in a puddle on her balcony. The burn area was restricted to outside the door, and it was just enough to melt the lock. But for all that it was small and precise, it still looked just like a ki-blast.
