Shiranui saw Titania with a Master Ball in her hand.  "[i]I needed someone that understood Smaug's pain so I called out the very Pokémon you captured in this mountain to have a little chat with him,[/i]" stated Titania before Shiranui could ask.  He smiled and Titania read a mental reminder for him to give Saisei a Poké Puff.  The Gardevoir gave Saisei's Master Ball back to Shiranui and Shiranui stowed the ball in a safe spot in his bag.
"Titania, return!"  He recalled his Gardevoir and resumed his trek through Mt. Moon, following Smaug.
