#ogerpon would be knocking on his door regularly to see if he can come out and play

We don't have Ogerpon's situation on Kieran's death, his absence, and the reunion.

I don't want spoil the current fic I'm writing but tldr: Ogerpon is indifferent

If you go by what happened in game, she doesn't know Kieran. The player character and Carmine never gave her the chance to get to know Kieran like she did with the two of them. Their whole adventure happened without him. He did convince the townspeople about the story of the ogre being wrong but that was all off screen. It probably took a lot of work and courage from him and Ogerpon would probably be grateful but that's like, not something she was witness to see him doing.

To me Ogerpon has the mentality of a child almost. It's hard for children to grasp what they don't experience. Yeah he would leave her little presents and stuff at her den when he was younger but she was hiding. She doesn't know Kieran aside from a vague oh he is nice. And then Indigo Disk happens and he is suddenly mean and mad to see her. She probably doesn't even understand why.

So yea Ogerpon being told post Area Zero that Kieran died she'd probably be upset because she understands death, her trainer died, so she would feel for Carmine and the MC because people SHE cares about lost someone THEY care about. There is a level of emotional disconnect there. She is sad in the sense that somebody passed away more than she is that Kieran, specifically did.

And Carmine does not handle that realization well at all.

There is more of course but you will need to wait and see.
