Chris forgives the bullies
In "David and Saul," when two bullies assault Chris at the subway station, steal his guitar, and then smash the guitar in front of him for spite, Chris naturally wants to take revenge on them (even ordering Gizmo to hack into the subway car the bullies are in so as to facilitate that vengeance)...but then Superbook takes the kids to meet David, who's on the run from Saul after the king has tried to have him killed. David later pulls this trope on Saul despite having a clear opportunity and the urging from his men to kill Saul; witnessing this, Chris decides that he'll do likewise to the bullies instead of taking revenge, as that's "someone else's job." That "someone else" proves to be the cops, who have footage of the bullies' criminal behavior from the station's security cameras and have come to arrest them.
