When Steph pulls away, Peggy doesn't do anything to stop it. There's something to be said in giving her control over the action. Control over something.

Then she asks it. Can I talk to you? And Peggy doesn't even hesitate. "Of course," and her voice is soft, her expression gentle. She turns to Steve, a silent plea but also not quite a request. "Would you take the couch for now?"

It doesn't even occur to her to take Steph out into the living room. She knows Steve is ill likely to be bothered by any of it regardless.
