You definitely weren't. \( ^_^)/

I'm pretty sure the Gray factor is to be discounted in this battle. Otherwise Cana wins by using a Sexy Gray Card. Or maybe a GrayxLyon Intense BL Card, which might actually make Juvia faint on the spot. ._.

Meredy is canonically the weakest of the 7 kin. Erza would have stomped her, but Juvia was actually a liability ... and Meredy was a kid. :/ So Juvia defeating Meredy isn't too great a feat, unfortunately.
