Just wanted to add my "Yes, that sure can be true" to all the other affirmations.

I also agree that by believing her and being supportive you could become a "safe" person for her and her alters.

I had alters that were in control for long time periods of years. And even with integration of so many (way more than 15) I didn't get all those memories back.

She is lucky to have someone who cares.
