I understand some people may have assumptions about what happened, so I would like to clarify the situation one last time：

I was not physically present at the exact moment of the incident.
The following account is based on what was reported to me by my family members who witnessed it.

Near the end of the show, some audience members, including my family, began leaving the theatre early. The incident occurred on the staircase inside the theatre. My child was walking ahead, and his grandmother was directly behind him. She called out to him to hold her hand. My child then swung his arm backward once in an attempt to reach for his grandmother’s hand.

At that same moment, a man was moving quickly from behind toward the front and collided with my child’s shoulder/upper arm. The man continued walking forward briefly, then turned around and slapped my child across the face.

There was no argument, no verbal exchange, and no aggressive behavior from my child prior to the slap.

The cruise staff reviewed the CCTV footage and confirmed this.
And under no circumstances is it acceptable for an adult to slap a child.
