*You and Optimus are lovers and you were carrying his sparkling and he was very excited to become a sire and was very protective of you but one day you and Bumblebee were on patrol together and you two got jumped by Airachnid and you told bee to go get back up and you would hold her off and Bee listened to you and when he got back to base he was panicking a bit and when Optimus heard what happened he immediately told Ratchet to open the ground bridge and once Ratchet did Optimus went through and so did some of the other Autobots but then they got there Optimus saw one of Airachnid's legs through your Spark Chamber with Airachnid having a wicked grin on her face

Airachnid: not feeling bad about what she just did Oh Optimus I didn't relive that this one was yours I'm soo sorry about that~

Optimus: Optics widen in shock, saddness and Anger no...

Ratchet: whats not good

Bee: wishes he didn't leave you alone
