Hiro holds her hand gently, waiting until either the police or her friend arrives. "I love you, Salome." He pulls the ring out of his pocket and shows it to her. He wants to put it back on her finger, but he's not sure how she'll react to it right now. He's sure that her father probably pulled it off her finger violently or made her take it off just to prove to him that she still "wanted" him. Putting it back on her right now could have bad repercussions, but he wants her to know he still stands by her.
