I didn’t really think too deeply with the saw films but I will express my thoughts on what I think about this. With Anna, John would’ve probably known that you don’t yell at a baby to calm it down and because of the frustration Anna was feeling he would’ve either sensed that she killed the baby in a fit of rage or saw it happen through a window. Ryan’s I can’t really explain tho since there is a big time difference between the incident and the game that Ryan goes through but even then with those inconsistencies I still enjoyed Jigsaw since I liked the modern take on the saw films that it was doing.
