Yup, going with Nick. Though it could be anything from Mavis to a Fairy to Layla, though I don't think it'd be the last, considering Mashima stated this arc is about Gray and Natsu; Layla would mean it'd be about Lucy too ... Still, with everybody meeting their parents, Layla would be fun too, I guess. :P
