>>50495735>Pikachu also recognized Lillie and not SerenaThis is actually a very good point. Pikachu picked up on Lillie scent not just all the way to the house but IN THE SNOW. Pikachu literally passed by Serena when it was with Ash and didn't even notice her.
Does anyone remember how it was with Misty and Dawn? Did Pikachu notice them before Ash did?
