Thanks Puzzle,
I think that is a good point, i.e. that alters are not always that easy to distinguish. It is an important thing to know. I have looked at videos of DID people on YouTube and some of those people have very dramatically distinct alters, but I have a feeling that isn't always the case. Actually, if you are going to try to protect the "system" it would make sense to try hide the "obviousness" of it to the outside.
