The post-credit scene that shows that Delia has hung a framed photo of her son Ash, his Pikachu and all his other Unova and reversed Pokémon at Professor Oak's Laboratory, excluding Squirtle and Primeape, onto the wall has been cut from the English dub of this episode. So, I wonder why you think?
From what I've seen in other series, post-credit scenes are rarely kept intact in English dubbed anime. I'm not sure why TPCi didn't just add that scene right after we saw Pansy and Satoshi take off on the airplane and before the credits when this episode initially aired, but I heard that the scene was posted on the official Pokemon Facebook account.
