The picture that i have attached appears during the commercial break. Around the time when "Who's That Pok?mon?" starts in the dubbed version. During the first few episodes of AG only Ash and May/Haruka were visible. When Masato appeared in the third ep, he was added to the pic in the same ep. When Brock appeared (I believe that was the 4th ep), he was added the picture too in the same ep, resulting the same picture that I have attached. (All right, almost the same. The real picture has a Groundon logo on the back, i've removed it for website purposes.)
Anyway during the Misty returning ep, she is not added to this picture. Does that mean Misty will not stay long with Ash and co?
