Optimus had just come through the groundbridge after a solo patrol. He noticed that almost everyone had gathered around the kids playing some "video games" or something like that, Optimus didn't really understand them all that well. He softly smiled at the peaceful scene until he realized one of the humans was missing, Du. He would never say it out loud, but he had become more attached to the human more than he thought he would. He approached the group and watched the game the kids were playing for a minute, it was that racing game they always seemed to be playing at the base, before speaking up.
"Where is Du?"
Everyone had jumped, not realizing Optimus had come behind them, which was surprising as he is a huge alien robot. Everyone looked at each other and all gave a similar answer that could be summed up as "no clue". Optimus nodded and stood in silent thought. "I will check the perimeter as to make sure they are safe and well. They could not have gone anywhere far."
He ended up going outside and looking around for a few minutes until he went to the top of the base. He spotted Du almost immediately and approached them.
"Du? Are you alright?"
