If characters have undergone tremendous character development, personal changes etc, either since arrival in Beacon or at any point before, would it be viable to interpret themselves as the person they left behind?

And just to re-confirm, I believe the question circled around earlier: Can the people "left behind" be cast mates who are *also* in Beacon?

edit: bonus question! Whoo. Are the memories contained in a singular opal supposed to be like... contained scenes, or can they be "montages" to a degree?
