What's the point of looking at John Fame's expression? He doesn't care one bit about Lissy Lock.
Otherwise, he wouldn't have admitted it so freely, and wouldn't have allowed Walter Smith to state everything so frankly.
John Fame no longer has to waste any effort on a matter that's already settled.
Even if he knows that she'll be heartbroken, he doesn't need to care or worry about that.
John Fame watched as Lissy Lock left. He could see her sadness and loneliness, but she just left.
He stood still, while Walter Smith followed her.
Looking at this, it's clear that Walter feels more than typical admiration for her.
All of a sudden, John Fame lifted the corner of his mouth again into a smile, but instead of self-confidence and satisfaction, it was a hint of melancholy and self-mockery.
Because he saw how Walter hurriedly caught up with Lissy Lock, his face filled with concern and worry.
John Fame just calmly watched.
