Pokémon Sun and Moon - Gladion's innocent phase

I would've liked it if, at some point, they delved deeper into the relationship between these two. Besides hearing about the regret Gladion felt for leaving Lillie behind with their mother, and witnessing Gladion's over-protective big brother instincts kick in when Hau complimented Lillie, we really don't know what they think of each other and how they behave around each other.

Geez moon! how thirsty can you be?!
