On Pokemon Black 2 / White 2, you can catch N's pokemon in the wild. Look at this log from Pokemon White 2:
A wild Purrloin appeared?!
Go! Vicky!
What will Vicky do?
[Hidden] used the Ultra Ball.
Gotcha! Purrloin was caught!
Purrloin's data was added to the Pokédex.
It seems like the caught Purrloin has a different OT!
And this is the same Purrloin mentioned above:
#509 Purrloin ♂ (level 7) OT: N ♂ (White 2, 2/0)
Timid - Unburden - 30/30/30/30/30/30 - Untrained
Scratch - Growl - Assist - ***
