Basically, Atomic Gaterode accepted the job to attack Byron house for the catalyst as payment cause it was supposed to be in his possetion. But in reality, although it was, Touko has destroyed it and used as an ingredient when she helped made the princesses beautie, everyone was shocked when Waver revealed she did that (even Touko cause she alter her memory to forget the event as part of her agreement with Byron). When question why she would do something like that, Waver answer thats just Touko personality, to do something so shocking just to see everyones face to what she laught and admit that yeah, that sounds like her. Apparently, destroying a catalyst that ancient and invaluable is something mages would normally never do, but Touko is a bit of an odd ball so...
