Lisa/River.
Lisa Cuddy hated headstrong people, especially House. This time however she was not as angry, which was probably because the woman who was trying to annoy her was River Song, a woman she had met when she was still in med school and who she knew wanted her to snap, although she had melted easily under the woman as she was kissed, passionately.
River had taken control the second she could do. Lisa willingly letting River take it, needing to let her control slip and moaning at River’s whispered thoughts, dirty thoughts.
