So as we all know Webby is April and this got me thinking why is she called April? Then i thought April is the 4th month so there's a possibility she was the 4th clone F. O. W. L made 3 others nicknamed :January, February and March.
It is a bit of a mystery; I wouldn’t have pegged Bradford or Black Heron as the types to give names to what were just pawns to them. May and June were certainly named due to their connection to/succession from April/Webby, but why Webby was named April is rather a mystery.
