It has been discussed before, what Grey meant by 'the Rent'.  It has been assumed that he was referring to his parent and that his parent was a naagloshii.  This led to debates as to whether a naagloshii CAN create an offspring and if so how and why.

But what if he wasn't referring to HIS parent? 

What if he were referring to Harry's parent?  Grey stated that he knew Margaret LeFey, and well enough to describe her as 'a piece of work'.   Meaning that she did somethings he would not have expected.

What if Margaret did something for him?  If he owed her a debt but couldn't repay it because she was dead, so he paid the debt to her son.

Having just been reminded that Goodman Grey knew Margaret, and Grey owed 'the rent', what if Shagnasty created a scion with Margaret?  It could explain how it got on the trail of Morgan.  Someone who knew about the relationship could have contacted Shagnasty and set him after not just Morgan, but his scion's half brothers.

Just a weird thought.

I was talking with a friend about the Dresden Files books.  He commented that Harry has done a complete 180 on the wardens.  At first he hated and feared them.  He resented the hell out of being conscripted into them.  Now, he noted, Harry seems to have embraced the role.

I told him it's because Harry grew up.  At first he was like our real world young people (we call them millennials today, but they have been part of every generation) feeling resentment that the world isn't the way they think it should be.  But as Harry has grown, he has learned and come to understand better why the council does things the way it does, why the wardens are like they are, and why Morgan treated him like he did.  And by understanding, he can become partner to it because he can see the necessity of it.

My question:  what other ways has Harry 'grown up' during the series?
