The big 5 of me rambling about my Casper ocs!
Maybe get some tissues cause you might cry (or not)
The Fishter Sisters didn't have another sibling. The three of them were plenty for their parents, but they did have a cousin on their father's side who they saw alot.
Their Cousin, Sherman Fishter, a bright and cheerful young man. Older by 3 years to Dreary/Diane. He didn't have siblings growing up, his mother was unable to after he was born.
He doted on his baby cousins. Loved each of the three girls as if they were his sisters, Treated them as his sisters actually. He loved them with all his heart and the girls loved him too.
They saw him as a older brother and loved playing games and drawing with him.
So when they all died, of course he was crushed. He saw their funerals go one by one. Basically destroyed his light a bit, since his beloved cousins were gone.
But he did live long enough to see his great granddaughter bore his cousin Diane's name and another great grandkid (the descendant from ramble 4) having the traits of his cousins
Giving him a sense of theyre always in his heart and with him always
