On the plane to Hong Kong, Craven and Zaylee York sat together, right by the window. Zaylee York sat inside and Craven sat next to her. On the aisle, there was a little fat man sitting.
Judging from his body shape, he weighs at least 180 kilograms, and his small eyes look very bright. After getting on the plane, his eyes kept moving towards Zaylee York, as if all his attention was here.
Craven intentionally or unintentionally moved his body closer to Zaylee York to block his sight.
