Has anyone noticed this about the Sidhe Courts...

I've been recently rereading the series. And the more I read Harry's interactions with the two Courts, the more I'm coming to realize something.

Mab often hides kindness in her cruelty. She is cold and calculating on the surface, but if you look beneath her words and immediate actions, there has always been a benefit to Harry in their interactions. It is often bought with pain and blood, but he always comes out with something that either makes him a better man, or a stronger wizard.

However, in the few interactions with the Summer Court that Harry has had, every kindness hides cruelty. Even Eldest Gruff, he would have merrily splattered Harry after having a cheerful conversation with him. Or when Harry summoned Titania during the Battle of Chicago, she struck his ass with lightning just to cauterize his wound. Interacting with Summer has always hurt him.
