I thought Wanda was his cousin...
Wanda is originally Wally's sister. In the English version of the games, she's changed to his cousin for mysterious reasons.
I gather she's his sister in the manga, as well.
Actually, I don't think so: わたしはミツルくんのいとこなんだけど、よく姉妹と間違われるくらい似ているって言われてるの。"I am Mitsuru-kun's cousin, but I am told that I resemble my sisters so much so that I am often mistaken for them." Or something like that. - 振霖T 22:38, 13 Mar 2005 (UTC)
That was in the manga? I don't remember that. Or was it in the games? --Ketsuban
