Not much happened, apparently there's only 2 locations (and therefore 2 gyms) avaliable: the New Island which seems to have Mewtwo as a Gym leader and Lapizula City... The problem is that I need Waterfall (i don't have the HM nor the badge to use it) to reach New Island and Lapizula City seems to be blocked by random scientists... guess I'll need to check a guide.
That should be all for today (sorry, i was really busy today)
