I love the way he descibes it, DID doesn't have to be something bad, it can also be something good. Maybe it is more like something extremely annoying for most of the people with DID, but I believe that as long as you keep trying to make the best of it, it can be something good (with the required downsides, though).
I don't know if Walker really got DID, but I also don't care, I like the way it's descibed

One of the comments says: "you don't have to be like Sybil and have different names and accents, you just have to have different "modes". Its like logging into windows with a different account, its the same computer but all the settings are separate."
