@Whatever yeah she did divorce him. Asked for the papers in advance and signed them the day she left. But they were still close friends and family for several years even before Diana died. The fact that Cassia up and left without a word and no indication of how she was doing or where she was going would be concerning to anyone who is friends with her. You don't have to be married to/romantically in love with someone to care for them and want to make sure they are okay. Or even just hang out sometimes. Also his son disappeared so he'd probably want to get him back at some point.
I'm sleepy 😴 🥱
