Given Yuun's general inexperience with tickling the poor Weavile cracked when David got his hands on him. In fact, he cracked so hard that his willpower started failing him. Before long David had managed to make Yuun sink into becoming a shrieking mess. However, David isn't without mercy too. Figuring he could use the Weavile, he offered him a job apprenticing under him. Yuun took up the offer, but has hit a few snags along the way. Unable to figure out how to use his clawtips effectively enough, he was resigned to being stuck with only feathers and brushes. Seeing his pupils dilemma, the Sableye offered to teach him personally on how he could handle his claws. Ordering Yuun to tie him up, the Weavile was surprised that David had placed himself in such a precarious position.

David has many tricks up his sleeves, however.

Having gathered a few magical artifacts here and there, the Sableye activated one stone that caused his soul to spring out and reside within Yuun's body. At the same time, Yuun's soul was tugged into David's body. Now quite helpless in the bondage he had just prepared, David took to showing his apprentice just how efficient his claw tips are. With Yuun helpless shrieking the former Weavile cannot help but wonder how long David intends to inhabit his form, or if he intends to even hand it back once this torture is done.
