Normally when he learned new spells, it was out of curiosity and wanting to try something new and different and rarely out of necessity; this time, he had the memories of the Mousse and the docks attack to drive him towards learning this. "You mean... an immediate incentive? What did you have in mind?"
He was willing to do anything -- or almost anyway -- to learn the spell as quickly as he could.
