I will say this. I loved the episode. But there was this theme of love in this episode. But it felt tacked on, since the episode was more aboout Twilight and her relationship with Celestia and the Mane Six.
Perhaps thats why Cadance and her love for Shining Armor doesn't feel as prominent for this episode.
The theme of love was only there for the ending and doesnt hve much to do with Twilight's own more prominent conflict.
