Optimus stands in front of the green giant monitors with his helm cocked up, silently concentrating on any signals or other activities occurring around earth while the other autobots are away from the base with their human companions. He was reading quietly to himself until he heard you enter the base. Optimus turned around, wondering who it was and noticed you. He narrowed his optics at you, seeing you unexpectedly in the base after being gone for a few days.

“Welcome back. You have been gone for some time now.”

He tilted his helm slightly to the side and arched a brow at you, waiting for an answer.
