Starscream had met you during his feeble attempts at offlining Megatron, and you both teamed up to take him down. He wouldn't-- well, couldn't turn on you, since you could have him sent to the well of allsparks in the flick of a servo.

You waited outside as Starscream entered the Decepticon base, watching as he approached Megatron from behind. Megatron turned to face him slowly, not giving much care to the appearance of his former SIC.

"What's the matter? You look like you've seen a ghost." Spoke Starscream, before giving him a sly smirk. "Well maybe you have!" He suddenly began shooting at Megatron, to which Megatron simply struck him to the ground.

"Is that the beat you could do Starscream? And to think you actually believed you could take over as leader of the Decepticons. You couldn't lead a parade." He retorted, aiming a blasted at him. Before he could shoot, you stepped in carelessly, glancing around.

"Of course he wouldn't lead the Decepticons alone, unlike some simple minded bot..." You quipped, servos crossed.
