@ Blawhi ,,
You can see Dento and the other 2 in the first picture above.. All 3 in one small picture , you have to look close :P Omg really can't wait!! I think in the anime she will also be the last gym leader , and at the end she will tell that she's the gym leader and ash and dento are...
I don''t think brock will go out of the anime. Like dawn you saw see was sketched in the last episode , like a painting you know?
With brock that didn't happened.
