I think he called your brother either because he knows he's been ridiculous or the lawyer has fired him because he doesn't want to be on the wrong side of a contempt charge or H isn't paying the bill, or they asked for a big retainer for what's coming up. In other words, BECAUSE DOING SO IS GOOD FOR H RIGHT NOW!!!
Yeah, pretty likely that his lawyer, who is probably fed up with him, gave him a preview of how this settlement hearing is likely to go, and H is trying to see if he can negotiate a better deal with you directly.
I wouldn't get into a big discussion with him, but your brother could tell him that he's free to send a settlement offer to you for your consideration. Then you can take it to your attorney to discuss. I'd get all negotiations in writing, I wouldn't talk to him directly. Don't give him the opportunity to try to manipulate you.
