It's funny how details like that are often overlooked when you read something isn't it?
I've slowly been removing the pieces of the janga tower that is Ben's mental state since Chapter 1. He wasn't ready, he thought he was, but the fact is he so wasn't. Benjamin just doesn't have the support structure in place. Or does he and he just doesn't know it's there and doesn't know how to use it? All I can say is, poor Benjamin. I have so much more to say about this character and where it comes from but I'd be giving too much away.
But I can say, with this story, 'the devil is in the details.' Even if that detail is in a few words buried in the chapter.
