Within 5 minutes in Desert Resort on White 2 I ran into, and caught, N's Sandile and Scrafty.

I didn't know what it was but I Googled it and found out he is their OT, I get all that and about the IVs. But is there anything special about them? Will it bring up some dialogue upon battling him with his own Pokemon?

tl;dr, Do I box these guys or are they important in any way?[/spoler]
