Interesting...as always, I like to throw things out for consideration, but they are just ideas....
If she said she went to sleep with a smile on her face, believe it. She FELT good about your "rendesvous"....
Perhaps on an unconscious level the whole role=playing thing triggered some echo from the past which triggered both the "solemn look" you caught and the panic attack.
Or it could be that now that she IS having needs met and feeling more IN your M, there's a part of her that's afraid...the part that's been trying to convince her that only the OG could make her feel loved "that way"???
Sometimes KAW, panic attacks just happen out of the blue.
It's probably best not to dwell on it, and just move forward...things DO look good right now.
