LL - thought I would just jump in for a minute. Have my own joint C session in about an hour...
As far as what to bring up for your first session? I would think that C would take the opportunity to get as much background as possible. Be willing to share time with H talking - you two will have different takes on things. I would see if C has heard of SBT and has read some of Michele's books.
Where I am at right now - I am mostly at peace but I do want so much more from W. I have doubts that W can ever do that but I do hope. And if it doesn't happen? I guess that I am OK with it - that it does not reflect upon me but it is all about W.
Hope I made some sense. And hope that you have a productive first session tonight...
