My mom-in-law was great. she works at a local business and after it happened the next time she saw me she gave me a hug and said she had no idea why or what her daughter was doing. She then went on to tell me she would not get involved but she was always there for me. Father-in-law rather cold but that has changed over time. We are still family because of the S8 and he's come to realize that.
As far as what to say everything is there, no reason to go into again with in-laws. Just be cival, take care of business and if anything is brought up then discuss but stay focussed and on task. It's better for everyone.
