A yellow Lamborghini drove through the rain, mud splattered across the lower part of its frame. Inside the car, a low growl was heard. "Tell me again why I had to go?"
Ratchet's voice responded. "Because, Sunstreaker. Optimus is on an Energon patrol and the others are with their human charges."
Sunstreaker growled again, speeding up. He didn't answer Ratchet, continuing to drive.
Not far away, a red mirror of Sunstreaker was having his own conversation. "Sideswipe, there is an Autobot signal approaching you. Terminate it."
"Yes, sir." Sideswipe changed course, ready to meet the Autobot.
"Sunstreaker, a Decepticon signal is approaching your location." Ratchet warned.
"Alright. I got him." Sunstreaker replied.
Ratchet huffed. "Do not attack him unless necessary!"
"Sorry…-chet, I… get tha-" For good measure, Sunstreaker added static to his words.
"Sunstreaker!" Ratchet bellowed. "Do not-"
The red Lambo was in sight now, and it transformed into the last mech Sunstreaker thought he would see.
Sideswipe.
Sunstreaker transformed, staring at his brother. His Decepticon brother.
Sideswipe launched himself at the mech, a blade already out, Sunstreaker blocked the blow, but Sideswipe didn't stop. He moved almost too fast for his twin to follow.
Thunder rumbled overhead as Sunstreaker fell to his knees. "Sideswipe…" he whispered. "Please, stop this." Sideswipe looked down at his brother, expressionless. Sunstreaker's Energon-smeared face was pleading. "I'm your brother. Your twin!"
Sideswipe stared down at him for a moment more, before barking out a laugh. "That doesn't change anything..." Sunstreaker looked up, his optics wide and fear in his face.
"Sides!" he cried.
"...'Brother.'"
