And if you could elaborate on what "Grey's events with the female adventurer trio" are I would appreciate it
Viewing post in I am having trouble with Grey's beach scene
The female adventurers are the genderbend guys of the party going on adventures. It happens when you advance the event steps of Trey, and later advance those of Brad and Grey to keep going.
