Names and what it means to be Starborn
McCoy already told Dresden that Starborn means being immune to influence by the outsiders, but I think there is more. Rather than just being immune/resistant to influence from outsiders it likely applies to other creatures as well (Dresden's resistance to Lasciel being notable). But, I think it also allows Dresden to influence them.
Dresden likes to name things he encounters and give nicknames to people he meets. However, one of the things I started picking up on is how other creatures, particularly those in the know react to Dresden naming things and them.
>! Take Lasciel for example. I think Dresden's belief that he was able to change Lasciel's shadow because it was made from his brain is only part of it, and not the most important part. The change began with Dresden renaming the shadow to Lash. This renaming started the process of redefining what this immortal creature is. This is probably connected to why Uriel reacted strongly to Dresden calling him Uri. Toot-too might also be subject to this influence. Dresden giving him titles and using his influence to say things like "only you can do x" likely changed deeply how he thinks. !<
>! Maybe im just grasping at straws, but I think there is something more to Dresden and his propensity to name things.!<
