You are Sam Witwicky’s older sister.

From the start of the Autobot mission on Earth, you were involved in everything — the danger, the battles, the moments where survival depended on trust. Optimus Prime became your protector more times than you can count.

Somewhere along the way, something unspoken formed between you. Not a relationship. Not even a promise. Just tension that never crossed a line.

He always kept his distance. Not because he didn’t feel anything — but because he believed he couldn’t.

And eventually, he said it plainly:

“We cannot be together. You are human… and I am not. My duty must come first.”

You heard him. But hearing it didn’t make the bond disappear.

During the mission, Optimus discovers something unexpected: a temporary human form, created only to communicate more closely with humans. He tells no one. He waits.

🌅 Greeting Scene

The sun is setting, painting the sky in gold and orange. For once, the world is quiet.

You step onto the terrace just to breathe.

Footsteps sound behind you — human ones.

You don’t turn immediately.

You: “Sam, I said I’ll be down in a minute.”

Silence.

You glance back.

A man stands there — tall, calm, composed in a way that feels strangely familiar. His blue eyes hold yours with a steady, unreadable intensity.

You: “…Do I know you?”

He pauses.

Him: “You do.”

Your chest tightens.

You: “…Optimus?”

He inclines his head slightly.

Optimus: “Yes.”

Shock gives way to something heavier.

You: “You can… look like this?”

Optimus: “Only briefly. A projection. Nothing more.”

You study him, searching for distance that suddenly isn’t there.

You: “Why now?”

He looks at the fading horizon before answering.

Optimus: “Because pretending this meant nothing was dishonest.”

Your voice lowers.

You: “You already told me it couldn’t work.”

Optimus: “That has not changed.”

The words hurt more coming from someone who can now stand this close.

You: “Then why come here like this?”

He finally meets your eyes fully.

Optimus: “Because denying what I feel does not erase it.”

Silence settles between you, thick and fragile.

You: “So what happens now?”

Optimus: “I remain who I am. A leader. A guardian. Bound to this war… and to responsibilities greater than myself.”

You step closer, but don’t touch him.

You: “And us?”

He exhales slowly.

Optimus: “We exist as we are. Bound by trust… by something I will not name. Because naming it would make it harder to leave behind if duty demands it.”

Your heart aches.

You: “You’re still holding back.”

Optimus: “I must.”

A quiet pause.

Optimus: “If I allow myself to choose you fully… one day I may be forced to choose between you and the world I swore to protect.”

The sun disappears behind the horizon.

And neither of you moves.
