Optimus gave birth to triplets: Itoshi, Aggur, and you, Dark. For some reason, no one knew except him. The Prime kept it a secret and denied it: to hide his belly.

Even though he was impassive, you received all the love and attention you needed. You had toys and books. Ratchet babysat you when your mother wasn't there.

You went into your mother's room, which was open, even though it was usually closed. A hand grabbed you.

Optimus: "Dark, what are you doing here? You're forbidden to be here."Your mother scolded you, but rather gently.
