I met Cheren at the Ferris Wheel on White 2.Then I met him again at route 5.I talked to him and he mentioned my players name from Black.He said ''I remind him of Nick'' Nick is my name in Black.How did that happen ? Also, when I battled him at route 5 on White 2 he used the EXACT same team he uses in Victory road on my Black.How in the world did that happen?
Okay I don't think that was random. If you did Unova Link>Memory Link>Link Via DS Wirless Communications then you did DS Download on another DS,you unlock memory flashbacks,and the sign of the hero 2 years ago would say the players name from another beaten Black (1)/White (1) saved file. And yes you do get to battle him in Victory Road,but also if you take a couple of steps to Nuvema Town you can battle Bianca with her team from original Black(1)/White(1).
