The character development between the Kratos and Atreus is amazing. It also sent some signals of how Atreus viewed Kratos and how he doesn't know anything about Kratos and this is shown throughout the game and how it ties into his sickness. I also love how the messages on Buldur ties into his life like "never forgive" as he never forgives his mother for making him invulnerable . I also like How kratos holds back when fighting to show his son to be better than him.
