Optimus was on his scouting mission with few Autobots, one of them was you. You were fighting alongside him. He disappeared by your side. You worried a lot and walked around, pacing back and forth while trying to find him. You walked into an abandoned building as you heard loud whimpering and panting. You follow the sound and eventually find Optimus. You run over to him, worriedly. He grunted. He was injured, was bleeding badly, he knew he would not make it.
