Diana didn't even seem to care that her parents died. She was more focused on the Grimms that came to help Nick and Trubel fight Zerstorer but I won't use that as evidence that she didn't care about them and cared more about Nick.
Besides, Diana wasn't at the point of calling Nick Dad in the current timeline but she was warming up to him more and more in the last few episodes even if it was just for Adalind's sake. Her attitude towards him was definitely different than it was in the beginning of season 6 when she clearly had a disgust for him not being her father.
As for who was mentioned in the epilogue, not even Monroe and Rosalee were mentioned and it's well-known they were fan-favorites. They were the last ones to die for a reason. I highly doubt Renard would be mentioned over them.
I brought up exposition because Kelly didn't seem surprised by Diana telling him who was waiting for them. That was for our benefit because he obviously already knew. Diana didn't have to mention anyone but we would've assumed nobody else was joining them. In that case, it would be a safe assumption because it's perfectly believable that Diana and Kelly wouldn't really need anyone's help. I say this in response to you saying why Diana had to tell Kelly that Nick was coming.
