Ok ..."damage done" - which is all relative anyway as to what you are prepared to "lose or keep" -
If they subpoena you for the JC then contact a lawyer and send them a letter which states that the lawyer will now be representing you and that he / she is requesting all the Documents/Charges/Evidence etc etc in preparation and that in the interim they refrain from making any remarks, announcements, gossip about you and your family.
This was my recent position too and they took flight ! [they have to send your lawyers letter to Bethhell and Bethal will respond by telling them to drop all proceedings, BUT they will still shun you [as good as if DF'ed] -
So ...what are you prepared to give up or lose ? It will be a Stale-mate position~
I was already being shunned totally so I had nothing more to lose ~
