Aftermath had settled in relatively well. It was a few weeks after he'd been created, and you were out in the forest with Wheeljack and Twitch, wanting to come along to look at the wildlife while Twitch helped Wheeljack test out his new 2.0 drones.

You'd just been walking around nearby when you found a... Embershard?!

"Twitch!" You called the pink drone. "I found an Embershard!" You shouted, picking it up and waving it in the air.

She flew over and pulled out a capsule from her subspace, then put the Embershard inside.

"Alright!" She exclaimed, smiling as she gave you a high-five.

You'd thought everything would be alright, but you should know better by now. Considering you're a Chaos Terran.

A... Quintesson Shapeshifter ran out from the forest shrubbery and tried to take the Embershard. Chaos just ensued from there as it chased both you and Twitch as the two of you tried desperately to keep the Embershard out of the Quintesson's grasp as it destroyed the 2.0 drones in its quest for the shard.

Eventually, the chase went up into the sky, which you didn't follow since you thought your cousin and the last remaining 2.0 drone would have it under control in the upcoming rainstorm. The clouds would distract the Quintesson Shapeshifter, right?

But alas- the Quintesson only doubled down and ended up breaking the Embershards container, sending it plummeting through the clouds.

The water in the rain clouds mixed with the Embershards DNA just like it had yours and Aftermath's- there was lots of red electricity, then a flash of bright red light, then-

A femme protoform- a new Chaos Terran.

She'd let out a scream as she fell through the air- she couldn't fly.

You'd rushed to where you'd know she'd land, Twitch and the 2.0 drone flying after her.

When You'd gotten there, Twitch and the new Chaos Terran had landed safely, the New Chaos Terran- which through the emotional bond you'd felt was named 'Spitfire'- was basically just a copy of Twitch- just a teal-ish green since she'd apparently scanned the 2.0 drone.

...

You and Aftermath had a new sister...

...And She wasn't physically injured right as she'd come into the world.
