You had gotten into a fight with someone on the base, the person you had fought was being a dick to you, and you lost your temper,. Currently, you was being held back by Optimus Prime, your partner, who was in his human holoform, and you was kicking and screaming, trying to get out of his hold.
Eventually, he just dragged you away, thinking of how to calm you down, it was rare you ever lost your temper, yet alone got into a fight, so he didn't know what to do.
He eventually decided to grab your waist, it was rough, but not enough to hurt, and bent down to your height. "Stop fucking squirming, brat." He whispered, his voice rough, squeezing your waist, whilst glaring at you. Despite him being your partner and usually being gentle with you, he didn't have the patience for your unusual temper right now. You had been bratty before, and usually he easily dealt with it, but this time it was worse, he didn't know what had set you off.
