Yeah, this is actually what I do when I get writer's block. I let my mind wander and random thoughts come to me. Like having Bluestreak be jealous of Narzenim when they first meet.

This "story" will have random prompts for random characters. I mean any characters. I have ones from Brainless Brute, Katie's Adventures, and other thoughts lined up for this. Readers can post prompts and characters, but since nobody reads this anymore, I'm not gonna hold my breath.

I haven't gotten to that chapter yet in Memoirs of a Brainless Brute, but basically Russ gets back (I'm not saying from where) and the Autobots basically tell her that if she can't remain neutral forever, and realizing that she had raised Prowl and had a maternal spark, gave her a sparkling they had found in the ruins of a city. So they pretty much met her, frowned, and gave her a sparkling and told her to raise it and bring it back. So Russ takes the sparkling - who she calls Bluestreak - off-planet to where she had been staying and raised him there with Jumper and Firebird who become his adopted older brothers. When he comes of age she returns him to the Autobots but he still considers her his mother.
Now Narzenim, she was really young with her parents on a space-flight when they were attacked by pirates. Her parents were killed in the fight but she survived and was taken by the pirates and sold as a slave. There she met a young mech named Strike who had also been sold and realizing how young (and weak) Narzenim was, Strike became her guardian, keeping an optic on her throughout their time. Russ was working as a bounty hunter then and hunted down their master and in the process freeing all the slaves. She finds Narz and Strike and take them in. Strike was renamed Fegali, which means protector in some Earth language. I don't remember which.

Jealous Bluestreak (Brainless Brute)

The first time he had seen the misshapen ball of fur he had felt a stirring of jealousy in his spark. That creature, the furry cat-girl was perched on his Mother's shoulder, surveying the world with scared green eyes.

He felt a deep sadness, too. He couldn't help but feel as if he was being replaced by an organic child who was no larger than his hand. But nonetheless he greeted her cheerfully enough, forcing a smile on his lips but retreating to his quarters the first chance he got.

Deep down he knew that it was unfair to hate this girl so much. His Mother had adopted and raised him because he needed her, and he supposed that she was raising this organic cat-girl for the same reasons. But that didn't stop the raging jealousy that he felt the longer he thought of it.

"Bluestreak?" he looked down at the be-damned cat-girl who stood, shaking in front of him. Her grey-spotted silver-grey fur was fluffed out like a wary cat, ears flat to her skull.

Even though he hated her, he felt a stab of regret. He didn't want her scared of him… He extended a hand to her and after a moment's deliberation, she crawled on his palm, curling her tail tightly around her avian-like feet as he set her gently on the table. Her guardian, the motorcycle-mech called Fegali was nowhere to be seen. Bluestreak said nothing, waiting for her to speak.

"Why do you hate me?" she asked. Her organic throat gave her a nasally accent as she spoke the query in Cybertronian though they were clear, precise, and scared.

He was honestly shocked and said the first thing that came to mind. "I don't!"

The girl's ears flattened tighter against her head. "You do." She said softly. "You avoid me and your feelings are hurt. Did I do something wrong?"

Curse her, she looked as if she were about to cry, wide black-lined eyes tilted upwards to look sadly at him. Bluestreak hung his head but couldn't bring himself around to admitting that he was jealous. "I'm sorry," he said contritely. And he meant it. "I didn't mean to be so rude. It was nothing you did."

She didn't look convinced but accepted it. Bluestreak noted that her guardian had come in looking for her, so it was likely she gave up because of that. For a moment he watched them walk away before looking back at his cube of Energon. He yelped when he found the seat across from him occupied by none other than Jazz. "Heya, Blue Boy!"

Bluestreak gave a shaky smile. "Hey, Jazz. You scared me."

Jazz jerked his head toward the doors where the girl and Fegali had gone. "Jealous?"

The gunner eyed him. "No."

The saboteur laughed warmly. "You have no worries, Blue. She still loves ya and would still love ya no matter what. Little Narz ain't gonna change that."

Bluestreak hung his head. "I suppose it really was unfair of me…"

Jumper appeared behind him, putting a massive hand on his shoulder. "Jealousy is what makes us fall. When we compare ourselves against others and find ourselves lacking we bring ourselves down for we are who we are, who we are created to be, and who we will always be no matter what jealous waves wash over us. Jealous is the bitter poison that twists our sparks into something black and evil." He said, quoting a wise proverb from the planet they grew up on. "Narzenim is really sweet. You should get to know your little sister." With a firm clap on the shoulder, the furred male walked away.

Jazz eyed the wolf-male curiously. "What'd he say?"

The gunner hung his head. "He said that jealousy was bad for the spark." He bit his lip, a habit he had picked up from his Mother. "He said I should get to know my little sister."

His companion grinned. "Tread carefully with her. She's still hurtin'." Easy as that he disappeared into the crowd and the shadows of the Jossine.

I should get him to teach me that, Blue thought as he finished his Energon. What'd Jumper call it? Shadow Walking? Shaking his head at his folly, he threw his cube into the recycling bin and went in search of Narzenim.

His little sister.
