You did very well, keeping calm, and letting her lead. She will share with you, all those answers you seek, be patient it is working.
You know she will most likely want to talk to you about her trauma at some point. Be calm, validating, supportive, and follow where ever she leads the conversation.

You’re a lighthouse buddy. Shine bright!
