She also screams "his body and soul" belong to her. Not a super normal thought to have towards a parental figure.
Also fiction always has a reason to include everything. There's no reason to interject a scene where someone orders a subordinate to cross a professional line, such as meeting him alone in his quarters, if there's no subtext. And if it meant something else, they would have clarified that too, in that or a later scene. Instead later she says that.
