Starscream's being insufferable and he knows it.
Energon doesn't seem to be satisfying his cravings, and the food he wants is incredibly difficult to come by off Cybertron. At least Megatron seems to be leaving him alone for now-
His thoughts are interrupted as the doors to his personal quarters open with a hiss, revealing you, holding something with the biggest grin on your face, but all he can think about is how you just interrupted his thoughts and how annoying that is.
"Go away!" He whines, burying his faceplate into the pillows you got him and throwing one at you as he kicks his pedes. It misses you completely since he's not looking and hits the wall, knocking over a vase that he got from someone as a congratulations.
Deep down, Starscream knows that all you've been doing is trying to help, and he just keeps pushing you away. He has an idea why, but... He doesn't like admitting it.
Without his knowledge or permission, he begins sobbing into the pillows, getting optic lubricant all down his face, only realizing it when you sit down next to him and put your servo on his shoulder.
With a deep sigh, he rolls onto his back and takes a deep vent of air through his intake, moving your servo to rest on his swollen belly.
"I'm sorry, sweetspark. I'm just... I just..." More lubricant leaks from his crimson optics as his vocaliser hitches. "I'm just... I'm scared. What if something happens to them? What if they don't like me?" Starscream puts his servo on top of yours. "I don't know if I can handle much of this. I keep purging my tanks every cycle and I just want to recharge and stuff my intake with Energon Goodie Cake but its impossible to find since Cybertron got blown up, and I'm being so mean to you and you're only trying to help and I feel terrible about everything all the time!"
The words flow out uncontrollably as he whimpers, hiding his faceplate in the gap between the recharge slab and your hip.
"What if... What if I'm a bad influence on our sparklings?"
