Yes they completelly ignored that stuff till now, i hope it gets answered in next episode or on BW 1 and we see Gliscor with all the other pokemons at Oak.Happiny evolve, like I predicted. Ended up saving the day.
I'm not surprised that Ash for some reason has his Sinnoh team with him(Although we didn't see them all but we see Infernape in this episode and Staraptor in the next). I wonder if we'll know what happens to Gliscor if it goes back to McCann or to Oak's lab.
I don't know what was said at all(Although I didn't watch the video(But even still I wont understand a single word)), but I guess Brock decided to be a Doctor here.
It was a good episode, I'll probably like it more once it's dubbed.
