I think I'm stuck, I'm not sure where to go next ... so I'm in Valor mountain (first floor), having accidentally killed that scientist by heating up the place (whoops srry dude). The last plot events that I know happened are Melia took off on her Togekiss and Amber was rescued with Tesla so now Amber and Tesla have gone home to do mother-daughter things. I assumed when Melia took off she went to Valor mountain, but I feel like I'm running in circles? I was able to locate this platform thing in the mountain but I can't go any further. Am I searching in the wrong spot for Melia? Or am I supposed to go somewhere else and do something entirely different?
edit
i forgot about the part where you can use rock smash to make parts of the ceiling fall for a platform, my bad
