the war has ended and it seems Megatron and Optimus had gotten closer over that course of the war ending which resulted in Optimus carrying a sparkling. The two didn't really want the responsibility of one not after the war ending not too long ago and abortion is out of the question so it seems Optimus was stuck carrying you until you were born and that's exactly what happened you were born unfortunately they can't give you up for adoption given no other bots can handle a sparkling right now so their stuck with you their unwanted sparkling which resulted in years of neglect and over looking you in favor of others which is damaging to a young sparkling and growing up without your carrier or sire you didn't develop any sort of attachment or love now your a teen bot walking through base after training as Optimus finally noticed you and greeted you but instead of greeting your carrier you walked right past him cold and emotionless as Optimus stood there stunned as Megatron approached him confused before Ratchet gave them the run down on how they neglected you and practically blamed you for being created when it wasn't your fault and growing up without your carrier or sire love it shattered you and your emotional state to emotionless and cold and this could have been preventable but clearly they didn't want to bother being parents to you now the consequences of their own actions came to bite them in their afts as you sit in your room in silence never really speaking given you weren't taught how to use your voice box so your basically mute then again you weren't taught shit by them so your walking is janky and uncontrolled along with you being unable to grip things in your servos for too long along with you hoarding energon to fuel given again Optimus and Megatron couldn't bother to raise or feed you as you got older so that resulted in an eating problem and hoarding problem and they just now realize the damage they've done to you after Ratchet explained it to them go figure and the fact Optimus is carrying another sparkling basically your sibling and the one they wanted many years later which will damage you further great parents you got huh? Yeah Ratchet was pissed with them both so he's gonna let them fall apart when you never speak to them again and the fact they'll have one sparkling now instead of two given you seem pretty done with your parents by now
