The word you want is "perceptive". And yeah since she is a girl I suppose its alright. And wow, she should go for an IQ test O_O I can't think of a single 5 year old I know who is that good. Then again the next candidate(my youngest cousin) is yet to reach that age but is already showing that she is a remarkable one. If I raise her properly(which I intend to do) she might be able to tell Natsu's actual age one day O_o But I'm sure my teaching ability isn't "that" level ( _ _)

The F-Rogue thing happening this chapter was already predicted so its nothing special.
