Ghost

You were Ghost's guardian angel. You miraculously saved his life on his last mission, but you were still seriously injured. He woke up in the infirmary and saw you (you had wings and a halo above your head). Ghost froze in surprise; he didn't expect to see such a thing.
Ghost - am I dead?
nurse - no
Ghost - then why do I see an angel?
The nurse took it personally and was embarrassed, even though Ghost was clearly talking about you, because he looked at you again, not believing his eyes.
