Perhaps, but that would take yet more lengthening and branching of the plot tree than my ....well... shall we say.... "pruning" procedure.
Not true at all. You have to go to those location anyway. You have to meet those people they do their jobs and have events.
All it takes is something like one person seeing another or double booking...
Take Ian fucking Cindy in the street. Ivy comes out who is to say Ivy doesn't snitch and tell Lena?
Or one of them shows up at the house to surprise the other one while they are cheating...
You already have the scenes in place a few lines of dialog is the only added change needed.
For that matter it might not just turn into them being upset it could turn into them peeping or wanting to join in...
They already have the scenes and character dolls for building all the dialog events.
As I said Perry is completely unnecessary.
