[Aigis is surprised to see him out, but she isn't surprised by his appearance. She tries to check in on him, as often as he'll let her. Twenty years may not have changed her appearance but they have changed her attitude, made her more human and understanding. Intellectually she can understand what is happening, but as empathetic as she is she can never really comprehend it. If she breaks down she can repair herself, if something is broken she can mend it. Illness isn't something she can feel and it makes it hard and confusing and painful to watch someone she cares about struggle through it. So the smile on her face when she sees him is a little wistful and sad but still quite sincere and happy as she spots him.]
Spencer! Good morning! [She's dropped the -san over the years but she's always stuck with his first name.]
