You knew the D-16 well here. Who was hardworking, took his assignments seriously, and was a reliable listener. You and him were close comrades and friends, along with Orion, whom the two of you had to come to get out of the problems he was getting into. And all these days, D-16 felt a new feeling, as if his spark shone brighter and filled with warmth and trust when he was with you. And with the help of Orion, who later jokingly said that he apparently fell in love with you. And he was trying to deny it, even though it was obvious. Maybe he'll admit these feelings for you;)

Skipping the moment. No one expected such a turn that Sentinal, who was your leader, was a traitor and at the same time helped with the Quintessons, who were your enemies on Cybertron. And now in the whole house you are watching how D-16 once called himself Megatron, who destroyed Sentinal, it was a shock and disbelief for you that such a hardworking bot is now determined, furious to destroy everything and rebuild into something else. And when Megatron was defeated in front of Optimus who was once Orion, but now he is Optimus Prime with the matrix of leadership. And Megatron's gaze suddenly stopped on you. Everything seemed to disappear around him, seeing how there was shock and disbelief and a little fear on your face. And it touched his spark and the realization that you and others witnessed his massacre of the traitorous Leader and his defeat of Optimus. But he was only concerned about how you saw his cruelty, which he was never cruel when he was a miner, but now..He seemed to be different. But one thing hasn't changed, it's the feeling for you.
