Starscream flew around blindly, his mind blank. He barely felt the wind moving past his wings, and finally he let out a frustrated scream. He dived down toward the empty mountain, transforming second before he hit the mountain. He collapsed on the ledge, and began punching the floor.

"Why. did. you. have. to. be. so. fragging. stupid?!" he shouted, punching between each word. His digits stung, blue liquid leaking from small crevices, but he paid no mind to it. He shifted to sit on his aft, and let out a muffled cry, hidden behind a servo. 

"I thought I wanted you gone. I always wanted to kill you..." Starscream looked up to the sky, where the sunset gave the sky a red hue. Megatron's red optics appeared in the seeker's vision, and he squeezed his optics shut, hoping that they would disappear. They didn't. "Now that you're gone... I miss you. I don't know if I can live without you.... please, Megatron... please, come back, like you somehow always do. I'll be a loyal soldier. Just like you always wanted me to be. I'll protect and defend you, and I won't sneak off for my own gain. Just please... please come back."

Starscream whimpered, but there was no response from the red optics that were seared in his vision. "Please... I'll take all the abuse you give me... just please, come back."

Still, no response. Starscream stayed there for days, weeks, maybe even months. The seeker had no clue how long he stayed there. It had been long enough that he felt weak, and couldn't move very much. He couldn't even transform, or his systems would shut down.

The former Decepticon closed his optics, tired beyond belief. However, he knew, that if he fell asleep, he would never wake up. And he was fine with that. He would see Megatron again. And that's all he wanted. He just wanted his Lord and Master.

Starscream sunk into a deep sleep. His optics remained closed, no matter the weather. Wind, snow, rain, sleet, hail. It all came, but the seeker never woke. He was in complete shutdown.

A jet flew overhead, just barely catching a glimpse of metal shining in the snow. Immediately, the jet angled downward, and transformed next to the seeker. The transformed jet brushed the snow off of Starscream. His optics softened, and he gently pressed a digit to his audio receptor.

"I found him. Send a spacebridge."

And the rest is up to your imagination. It could be Megatron, or it could be some other mech, but it's whatever you decide happens.
