I will say, this series is a really good example of adults being trustworthy, present mentors to child protagonists without getting in the way of plot action/progression.
There’s a few key moments when an adult withholds information at the time, then reveals it later at a more appropriate time (in a good way). (I’m looking at this is direct opposition to say, Dumbledore, who is kind of the worst).
The adults in this series make a fair effort in taking responsibility and handling the big stuff, letting the kids be kids.
My one exception to the good adults is [R’s Mum] who crosses a fair few lines in the book she’s introduced, but an understanding is reached and she becomes an example of flawed adults and things not being black and white.
