The bad thing about his curse was that his power was quickly growing, and couldn't be contained within his child form. He had to get the curse to break if he was to live... and if Belldandy was to live. Well, in the end, Belldandy finally speaks his name. However, Welsper then hacked into Yggdrasil, and was punished afterwards by being reincarnated into a cat. Still, though, he cursed himself AGAIN in order to remember everything and keep his intelligence. So he still lounged around at Tarikihongan in cat form, but Hild found him, seeing his punishment living as a girl cat.
