I could see one. Today, we have many who have the Kanto/Johto Pokemon who evolved to Sinnoh, at the late dex. Why should James be singled out? And when had James had three Pokemon last time? He had Cacnea, Carnevine and Mr.Mime jr, but Cacnea got sent to a place, where it might never show up again. I think James could have a Tangegrowth rivalry with Carnevine. James should also realese Mr.Mime jr and get something fresh. If it's a Psychic, I could see a Bronzor! But hard to tell, since I can see them get a new one in the filler region. No new one now, but later, I can see something catched.
