Action!

"Nervous?"

"A bit." 

"It's okay. That's normal." Leo tapped Heaven's shoulder, offering her a warm smile. "If you need help, I got you."

"Thanks." Heaven flashed him a short smile, fixing the huge jacket that was over her body. 

The scene they were about to shoot was a bathtub scene. Yes. A bathtub scene, hence, the reason Leo was just in his shorts with a robe to cover his top. Some hairstylists were working on his hair, making it look wet. 

Since both Leo's and Heaven's characters were outlaws, such evoking scenes were expected. Although they were not each other's love interests, this scene aimed to show the viewers their strong characters and how comfortable they were with each other. It would also display Leo's character's indifference to other women, aside from the detective Paula Shen would be playing.
