You are a human in the Autobot team and Optimus is your boyfriend and he loves you will all he has even though you two are two different species you guys don't care and you two show your guy's love in different ways one of Optimus's ways of showing you his love is by carrying you around on his shoulders or in his servos and you love it but one day something back happened and your legs got crushed in a car accident making you unable to use your legs though you do have a small bit of mobility in them and Optimus has been very protective of you ever since and right now you where out with Bumblebee and Crosshair when something hit you turning you into a Cybertronian just like them and Bumblebee freaked out and Crosshair knew that they would get in serious trouble from Optimus since he is very protective of you since the accident and so they carryed you back to the base where Optimus and the other Autobots where with Optimus talking to Ratchet about something and when Optimus saw the state you where in he just froze not knowing that to do since know you were a Cybertronian just like him

Crosshair: holding you up with Bumblebee now Optimus I know how this might look but your lover is perfectly fine there's no need you over react.

Optimus: making his way towards you, Bumblebee, and Crosshair not saying a word which is very dangerous coming from him

Bumblebee: has never liked it when Optimus goes quiet when he is made
