Headcannon that out of boredom some avatars created very complex betting system on Peter and Elias and their marital status.
There are several categories like who will propose this time, who will ask for divorce this time, how long will the marriage last, how long will the divorce last etc…
Peter has no idea something like that is happening but Elias is aware and sometimes asks for divorce or proposes just to make someone he doesn’t like lose.
