Yes, definitely possible. One of the others here, whom some of you may know here as Myele or Myorp, has this continuum thing going on where her personality shifts on a spectrum and on either end she most definitely qualifies as different people. They even talk to themselves occasionally inside which is somewhat confusing for any of us who happen to be listening at the time.

Kent, one of our original insiders, also appears to exist dually, although that's quite odd because they are both pretty much the same person for all intents and purposes, just that there are two of him. They echo each other alot whenever either of them is talking. Almost like you could imagine a two-headed man.
