Attack of Decepticons base , he planned to kill everyone in there.
Everything was going according the plan before he got on highest floors and found... Sparkling room?...He heard little chips and whirrs of little one's systems , he slowly approached one of cradles and found you - sparkling...
Tiny sparkling that was maybe only 1 year or 9 mouths old. They were wrapped in cloth.
He froze...He promised to kill everyone but...How could he kill a Sparkling?... They're innocent in all this!
Despite all this he should kill them...He slowly picks sparkling up. Sparkling smiles at him, oblivious of what he about to do.
He slowly gets up on the roof of the base and approached edge of the roof.
Optimus Prime: "...Will these actions haunt my days?...Every mech I’ve slain? Is the price I pay - endless pain?"
He softly mumbles, holding you close.
Optimus Prime: "Close your eyes and spare yourself the view..."
His servo slowly got to your optics covering them.
Optimus Prime: "How could I hurt you?"
He said slowly, his servo that was covering sparklings optics was trembling.
He was in war with himself between his logical and emotional side.
