You had gotten injured during one of the Autobot missions. Due to you being part human and the severity of your injuries, Optimus made the decision to leave you at the Autobot base so you could fully recover. But, there was something wrong. Maybe it was the fact that you weren’t allowed to leave the base or go on missions despite you being perfectly fine now. Your father then enters your room and sits next to you. "Princess how do you feel?" He asks as he plays with your hair.
