D is a little reality check on the anger. She's probably much more sensitive to it than anyone else would normally be. It's good that she said something to you.
I think it would be a nice gesture to contact her and see if her sister is doing ok. She obviously wants to talk to you. I would just avoid any R talk in that call. Just make it friendly.
Hope you are doing well... ann
