[He pauses to think for a moment, before the name actually connects with a face.] Oh! The lady with dark hair, the one who was smiling a lot! She's... not here anymore?
[The happy look he had (he liked her!! they got along well and he always looked forward to seeing her and talking about their shared love of books...) changes into that of sympathy.] Sorry. She must have been an important person to you. [For you to look like that.]
