In Chapter 14, Sirius makes a bold and dangerous appearance in the Gryffindor Common Room fireplace, which gives Harry, Ron, and Hermione the novel opportunity to exert some control over an adult figure. Though they are very happy to see Sirius, they worry he’ll be caught, particularly since the last time Sirius appeared in public, at the Kings Cross train station (as his dog counterpart Padfoot), he was recognized by the dreadful Malfoys. When Sirius suggests that he might join the students the next time they visit Hogsmeade, Harry, Ron, and Hermione all agree it’s far too dangerous. Here, the children are refusing to allow the adult to do something they feel is too risky, which suggests that in some ways they are able to think more clearly and wisely than the adults who purport to know best.
