At the end of Chapter 2, It Gets Personal. At the end of Chapter 3, they see what they're dealing with. Here in Chapter 4, they have a clear goal of 'stop Remora's 'I'm going to be evil because it's fun to hurt people' plans' and 'we're in a unique position of knowing all this stuff about these bad people so we are the only ones who can stop them'. I... hope that made sense.
