Optimus watches them, the human race that he has started to hate.
Yet, a few, he reasons, are still good. He watches Cade and his daughter Tessa, sneakily holding her boyfriends hand. But mostly he sees Bumblebee and Crosshairs discussing something and Hound laughing at them. A haiku falls from Drift's lips and Lauren looks up at him, nodding when he asks if she likes it.
The sun shines on her head and for a moment Optimus thinks about how he loves her. No, he is certain. He has come to love the young woman.
She looks back at him, green eyes turning to look into his optics, full of laughter. She grins at him and then turns back to the road before them.
The sun bathes her in a halo of light and he blinks, the sun warming his metal skin. He even fels warm inside.
Perhaps it's not only the sun, but perhaps, the way she smiles at him does the trick too.
