That's right, Haruhi! [Spot on, have a gold star.]

Alright then, Lupin. My name's Duplica, those other girls out there that look like me are my Dittos! Ditto and Mini-Dit.

[It doesn't take long for her to look past Lupin and find her two Ditto out there in the plaza. She even points them out, just in case Lupin doesn't know where they are... But also to see if she can make him turn around for a second. That's all the time she'll need.]
