Starscream

[Have a voice that's kinda screechy in a way. And also slightly overdramatic as he realizes what's going on.]

What?!

This is impossible! I refuse to believe something this ridiculous.

[It couldn't be real. What the journal said defied all scientific reason. Not to meantion something seemed highly off, like he was altered in some way ...

...

That blasted medic better not have done anything to his processor when he was at the Autobot base.

He had no other explanation for what was going on. A moment ago he was dumping the yellow Autobot kid on a beach while Jetfire flew off to play cliche stupid sacrificial hero. And now? In a cell. With an oversized book.

The only possible explaination was that Ratchet uploaded a virus into his systems and this was all one giant hallucination.]

I will not fall for some idiotic Autobot trap!

Do you hear me?! I don't care who you are. You are not fooling me with your lies.

[It should be noted that he's actually talking to the air as he has not actually figured out that the journal records him.]
