Jesper is a chameleon in general, but in this way that adaptability is most easily perceived. He can be a different person to everyone he meets, but at his core he still is himself too. It's never him pretending. Inej has been his best friend since the moment he met her, and after the life she had, he would break the neck of anyone who looked at her wrong. And break the legs of any person who didn't respect her boundaries in a romance. He'd have to break his own legs, and probably would, if that ever happened.

Instead they always seem comfortable and on the same page. He lets her lead but not because she is made of glass, if anything giving her full say over everything is about how she's made of steel. Jesper likes women who have power over him, in all honesty, not that they've joked about that yet. It's probably implied.

"A silver-tongued devil, I know." Jesper leans in to give her a soft kiss again, so they both can get a nice little taste together. He leans back to look into her eyes. Dark and beautiful, windows to a beautiful soul without compare. "How are you doing, my love?"
