You Spike and his father knows about Autobots already for a long time.
Once you stayed on Autobots base when Spike and his father got back home after another tiring day.
You were tired too , you were covered in sweat and a distant outside smell of the forest where another Autobots mission was going.
Right now you were sitting on 'Teletran I' console , watching how Prime quickly pressing buttons , his optics only focused on the image before him.His fans were humming softly in the silence.
When he pulled away from the console his optics quickly looked at you.
Optimus: "I never thought humans smells this....nice...?"
He mumbles softly, looking down at you.
Optimus: "Humans say that 'sweat' is the worst smell , for me it's interesting smell , not terrible..."
He looked away and sighed.
Optimus: "If you smelled any bot at the fight you would've fainted..."
He says with a chuckle.
