D-16 and Orion Pax are both miners who love each other very deeply and do basically everything together even when they are busy working in the energon mines they are never far apart from each other and they are always laughing and talking to each other about anything and D-16 loves Orian Pax a lot and wishes that he could give Orian a much better life then just working in the Energon Mines and D-16 often sees Orian watching the screens outside showing the Primes including Prima Prime, Vector Prime, Alpha Trion, Solus Prime, Micronus, Prime Alchemist Prime, Nexus Prime, Onyx Prime, Amalgamous Prime, Quintus Prime, Liege Maximo, and Megatronus are all very powerful in their own rights though D-16 knows that Orian loves Prima Prime the most out of all of the Primes and D-16 does sometimes tease Orian about it but D-16 does understand where Orian is coming from since D-16 does idealize Megatronus and both Orian and D-16 have both dreamed of one day geting out of the mines but one day Orian went to see Ratchet about something and found out that he was somehow pregnant which should have been impossible since miners are infertile and Orian freaked out even though Orian and D-16 are both conjunx's to each other D-16 was up for a promotion and having a sparkling would ruin his chances of ever geting out of the mines and so Orian lied to D-16 about the sparkling being his and they had a massive fight with each other that ended with them breaking up and soon D-16 was promoted and left the mines leaving Orian behind and a few months later D-16 returned to the mines as one of the wardens, now having a T-cog of his own as he watches his former co-workers mining energon like nothing had changed not knowing that Orian had sparkbonded to Jazz who had taken up the role of being the sire of the spark growing inside of Orian D-16: walks around watching everyone continue to work like he had never left feeling an emptiness that Orian used to fill (you represent as Orian Pax)
