Megatron's comments sort of hit a nerve, but probably not for the reason he would think. Starscream shifted his gaze back at the former warlord.

"You sound like someone I know," he responded, his optics briefly glancing at the Autobot symbol on Megatron's chest.

Starscream gestured towards the sky.

"The sky up there is an illusion created by light reflecting off particles in space. A normal illusion compared to what we saw before but one nonetheless."

That was followed by a bit of a smirk.
