Starlight reveals Thomas' past

This is how Starlight Glimmer reveals Thomas' past in Starlight Glimmer's Revenge.

[we view Thomas and Starlight Glimmer, face-to-face. Starlight prepares to use magic on him but suddenly stops]

Starlight Glimmer: You should've discovered your past long ago, OpThomas Prime.

Thomas: What do you mean?

Starlight: I mean, [sighs] Primus was only trying to protect you. He didn't want you to find out that you were a Train-Prime. So, now that you have, every Deceptitrain in the universe is after you.

Thomas: No way! That is a lie and you know it!

Starlight: Enough! No it's not! I am telling the truth!

Thomas: No. Then, I'm just...

Starlight: A Train-Prime who has already begun his journey, only.

Thomas: No. This can't be.

Starlight: Besides, Primus would never select an engine who doesn't know a thing or two about his Train-Prime past. Why an engine at your age, you should've become a Prime long ago. [leaves]

[Thomas looks at his scratched Autobot logo. He touches it with a hand then looks at it. It's black]

Thomas: I... I can't do it.

[Twilight Sparkle peaks out from the shadows and gallops over]

Twilight: What did you say?

Thomas: I can't.

Rainbow Dash: [comes out of hiding] You... are... Thomas.
