The Shining - Figure expression

Looking at jack torrences character
He doesn't change expression when his wife tells him his son has been strangled. He seems empty, emotionless and as if there isn't anything going on in his head. The way he walks around shows and lethargic nature and physically and emotionally drained. Then he switches when his wife says if they should get their son out of here. He gets angry and overpowering. Also he starts to look at things with angry eyes. Both of these personalities show his mental breakdown at different stages.
