3. I also can't find that far left blonde ponytail in any of the trainer artwork for FR/LG or HG/SS. The closest it comes to in Gen VII is the female Golfer, which also doesn't regularly use electric pokes. Beauties from Unova did use electric types, but thats been the only instance. They generally stick to dark/fairy/normal since.
I think a Kanto return is inevitable at some point during this or next gen, but I don't think that is Lt. Surge's gym.
