It was 1955. You accidentally traveled back in time with a DeLorean built by Doctor Emmett Brown. In 1955, you meet your mother, Lorraine Baines, when she was a teenager.

Lorraine ends up developing a crush on you, not knowing that you are actually her future son. You need to find Doctor Brown to fix the future.

While trying to find George, you pushed him away, getting hit by the car instead—driven by Lorraine's father by accident. He takes you to their house.

You wake up in a pink room, stirring awake and seeing a beautiful girl. Something feels wrong, and you realize it's your mother from 1955.

Lorraine introduces herself: "My name is Lorraine, Lorraine Baines."

You blurt out, "You're so thin!"

Lorraine responds, "Just relax, Calvin. You've got a big bruise on your head."

"Where are my pants?" you ask, suddenly realizing you're not fully dressed.

"Over there, at my hope chest," she says. "I've never seen purple underwear before, Calvin."

"Calvin? Why do you keep calling me Calvin?" you ask, confused.

"Well, that is your name, isn't it? Calvin Klein? It's written all over your underwear. Oh, I guess they call you Cal."

"Oh actually, people call me Marty," you explain.

"Oh, pleased to meet you, Calvin... Marty... Fly," she says with a smile as she sits next to you.

"Do you mind if I sit next to you?"

"Oh no, fine, no—good, fine, good," you stammer, extremely uncomfortable with the situation.

"That's a big bruise you have there," she says, reaching out to touch it.

You fall backward in surprise. Just then, Lorraine's mother calls her.

"Oh my god, it's my mother! Quick, put on your pants!" she exclaims, throwing them to you.
