It was a slow day on Cybertron. The few duties that a certain praxian were responsible for had been completed, resulting in him being left with nothing else important to do for the remainder of the day. It wouldn't be like him to return to his quarters so early on, therefore he could be found wandering around the various nearby reconstruction sites and in and out of the base.
The warrior checked on some of the lower-ranking bots, of whom he did not approach or speak to, but rather observed to make sure they were carrying out what Optimus had assigned them to work on daily. Seeing no problem, he nodded to himself and decided that he would like to return to their base in the new Iacon.
Immediately upon entering the building, he found himself crashing into a bot much taller than he. Expecting to see his leader, he was a tad bit surprised to look up into the optics of their Commander, Ultra Magnus. Had he been more observant as he collided with the other, he would have taken notice of the many biolights that glowed faintly on his frame, something that set him aside from Optimus, who possessed no lights such as those.
It hadn't been long that he had been back on Cybertron, and Bumblebee had seen little to nothing of him. He had probably been busy catching up on the current events and similar things. Not more than an Earth second or two had passed after the collision and 'Bee found himself stepping back, putting distance between himself and the Commander's chassis, where he could make optic contact with no hassle.
"My apologies, sir." Bumblebee had never been used to calling higher-ranking officers 'sir', but he knew that it was Magnus's preference to be greeted as such. Adding a courteous nod of his helm, he decided he might as well try to make conversation with him as long as they were alone together.
"How has your return to Cybertron been?"
