I discovered this site while trying to clarify a doubt I had which wasn't answered here. Maybe someone can help me. In a conversation: Hey Lucas, who's she? (Lucas says: Who? She? Ah, she is Laura.) Isn't the "She" in "Who? She?" wrong? It sounds really off to me. I think it's like saying: Who are you talking about, her??? [Object pronoun] (That girl over there???) So you would refer to her as HER and not SHE. Is that right or am I missing something here?
