"Finding Felcandra" Where can he hide? I don't really understand how to unlock Lewis' Chimera
In mingle 2 they can be found in the busts in either the banquet hall or parapet. In mingle 3 they are hidden between tree branches near the center tree in the courtyard (they're colored green). If you choose the correct dialogue options for both of these and are still in a form that's "yourself" (usually ones that don't have a name change), you can choose Felcandra during the date challenge where they'll appear hidden in a bust during the date selection screen above everyone. Afterwards there will be an option when the mirror pool is introduced if you did the date correctly
