"It is very important. It is why you now have powers Chat Noir and the others will not have access to yet. Hinamori-san had the Humpty lock. It has the power to allow some special charabearers to fully transform. Most people with Shugo Charas can only chara-change. That is when the chara takes over an aspect of their personality and gives them increased skills. Usually the child doesn't have much choice in the matter for reasons I can get into with you when you are older." Mostly because he doesn't want to discuss it now, and that's a tried and true dodge for adults (tm).

"Some bearers, lika Hinamori-san and Utau Hoshina Can Chara-nari because of exposure to the lock. While your Miraculous and Kwami are not quite like a chara egg and chara, the powers share many commonalities, especially at the root. So while this won't give you any powers with Tiki... it will give you a new what to charanari."
