Proffesors Juniper's Pokemon question?

Question

First of all when you start Black/White Poff. Juniper shows you how to catch a Pokemon.She battles a wild Patrat with her Mincino and she catches it.Later in the Black/White 2 games when you go to Proff. Juniper's lab in Nuvema town there is a Cincino and a Watchog.Did Mincino and Patrat evolve within the past 2 years ?

Answer 1

That is a possible theory but it hasn't been revealed yet. I don't really know about the watchog but the cinchino does make sense especially since its present during the lecture in the beginning of the game. It's a good theory though
