Ralph’s ass will be chapped over that for months. He can’t be mad at Daddy Dick, the guy who he covets and who actually snubbed him, so Digi gets all the invective.
I get the idea that Ralph is devoted to May because he is relying on her to have a “regular job” and he can’t afford the rent/expenses at the new rental house alone. Being a expense-sharing roommate is truly the way to get Ralph’s love and loyalty, not having his child. Faith was never a desirable partner for Ralph, he wants and needs a woman that takes care of him.
He will forever mourn losing a mate with the earning potential of Nora, greatest tragedy of his life.
