"You summon them?" Raiden has been called on many occasion, but he doesn't always answer if it's not a situation he needs to appear.
The idea of being summoned, however, is strange. To think of a natural element at the call of a mortal. To have the element's energies tapped made sense, but to be controlled or commanded?

"I know you mentioned a garden, but are they not free to see to the realm's upkeep?" He's not intentionally ignoring her question....not entirely, anyway.
