I think that maybe Cora has something to do with this…
Even if it was just scheduling issues that meant the actor couldn’t be there, I’d love it if they used this to create another thread of the story in the future, showing that Cora had him distracted by business in another realm to ensure that Eva’s death had maximum emo impact. Poor Snow shouldn’t have been there all alone to grieve for her mother. There’s gotta be some reason why her father was absent for that. Something that wasn’t in his control.
