Yes, totally. There are different groups of alters in here and some groups have always had some knowledge of others. Like the two that first presented themselves to the hosty one were two child parts - one older, one younger. The older one had always protected the younger one. And the older one was quite aware of the hosty one. Some alters had little awareness of others, and some had more. But the hosty one of the time was in denial about the DID for a very long time - she swung back and forth between acceptance and denial for years, even when the evidence was slapped in her face time and time again.
