multiplicity_archives | First time poster and a question

Hello, all. This is my (our?) first time posting to the community, though I'm a long-time watcher.

Doing a little poking and prodding around my system (one original multiple, two soulbonds), and in the last 20 minutes have redefined what sort of system it is, as well as discovered one lost 'tenant' and noticed that one other has... 'phased' is the best word I can come up with... from one name and 'face' to another, but is still essentially the same personality.

Okay, rewording the question:

Has anyone else out there 'looked away' for a time, then come back to discover one of their bonds/personalities has become a new person, but their essential personality has not changed in the slightest? I'm finding it to be an interesting phenomenon.
