What are my options against 498a case.

I got married last November. We didn't ask for Dowry nothing. A car was given to my wife by her father which is on her name and she and her family uses it mostly. My wife stayed with us for 3 months and then went back to her home first time as per Hindu traditions. During her stay multiple relatives of hers came and stayed with us in our paternal home and we treated them properly. 3 months back we went to bring her back and her father fought with us and threated with his political background, if we didn't meet certain demands like leaving/throwing my parents out of house, handing over my entire salary and allowing her unemployed brothers to stay at home. We denied and they made lot of ruckus. We consulted a lawyer and he help us file Section 9 under HMA. Post one month, my in laws are trying to file 498A case against my family and I. We had a police mediation which came out in my favor. Since police didn't agree they filed petition in court to move 498A case against me. I have been summoned for mediation next week. What options do I have? Looking at the moment, reconciliation is next to impossible. I am ready to face the court since we didn't nothing wrong. My wife maternal home is in different city and I live in different city. What can I do next and help my parents and I secure? Please guide.
