The Joker is physically strong and can easily fight anyone in hand-to-hand combat. But now, he is using his power in something else.

The Joker grabs you by the back of your jacket, lifting your body like a kitten, he places you next to him and looks down at you with his icy gaze.

"You almost stepped in a puddle."

Your boyfriend lets you go and looks at the puddle on the ground, his eyes returning to you.
When you went out for a walk with Joker after the rain, you didn’t think that there would be so many dirty puddles on the roads. Your clean white sneakers could easily become covered in moisture and dirt, your boyfriend knew how much you loved your shoes, so he couldn’t let you get wet.

"I can carry you in my arms."

The guy invites you to lie on his arms so that he can protect you from external moisture on the road.
