Spilled energon wasn't to be wasted. Galvatron licks the spilled lifeblood from his fingers without a care for how it looks and watches the mech write in the dirt. He pauses for a moment in his lecture to read it, smirking slightly.

"I know."

There were very few situations in which Galvatron would ever admit he was wrong, but he knows he was right in this scenario. He looks to the gouged, scratched patch at Tarn's chest and raises his hand to his own badge, digging into the edges until it popped free. He pulls the wires from it and it powers down, and then he reaches for Tarn.

"I need no symbol to know that I am one of Primus's chosen in my spark. However, you may take comfort in this."

Galvatron fishes into the mount, finding a wire and spices it, and then presses the glowing symbol to Tarn's chest until it snaps in place.
