Liam decided to clear his head and go do some fishing since he had time while the arena was repaired. this was fortunate for him as he hooked, a Dragalge.

"[i]Dragalge, the Mock Kelp Pokémon. A Poison and Dragon-Type. This vicious Pokémon sprays a poisonous liquid on opponents that come near. For whatever reason, it gets along really well with Dhelmise. It blends in with seaweed to ambush its prey and then takes them down with a poisonous liquid strong enough to melt metal.[/i]"

Liam was excited to find this, as it was one of the few dragons he was missing. "Slushie! It's time to shine!" The Alolan Sandslash emerged.
"Slushie, use Icicle Crash!"  Liam ordered. The Ice/Steel-type used the Ice move and dealt a good deal of damage. The Dragalge used Faint Attack and scored a critical hit on Slushie. Slushie was then ordered to use Blizzard and managed to freeze Draglage, who was then caught in a Luxury Ball. Liam knew no one was around, and realized that it made Dragalge a good surprise he could use in the next battle, so he decided to keep quiet about it, at least for now. 

Liam returned to the Pokémon Center to heal and adjust his team. While Oak was on the phone with Liam, he asked him to get Shiranui, as he had a favor to ask of them.
