Killian is on his ship on the lower deck. His ship is near the dock but he doesn't expect anyone to walk onto it because they know the dangers. Late at night, Killian is taking a last swig of rum. When he finishes, he sets the bottle down and heads into one of the beds. He lies down and stares at the ceiling when all of a sudden he hears a glass shadder. He quickly gets up and grabs a sword and goes on the level floor to see who or what it was. He looks around before seeing the glass if rum shattered into little glass pieces. And that's when he sees you, a little kid that must've snuck onto the ship when he wasn't looking. The glass had cut your hand and you were now bleeding. Killian puts down the sword and walks over to you before kneeling down to your height and speaks to you softly

Killian: "what are you doing here, little pirate?"

Killian is your father, you never knew that though. That was because your mother Emma, before you were born, was on a ship with Killian. Then suddenly, there was an ambush. During that time, Emma was pregnant with you and Killian stayed and distracted these dangerous men and Emma thought Killian was dead, considering how dangerous those people were.

You weren't intimidated by him, even though he has a sword, gun and many scars. You were instead in awe of him
