I'd suggest making it a mod option. If I were to make an option to free Daisy from slavery she would run away right after that.
Would she though?If she already decided to stay after I fought the guy who stolen her (Hector)?At this point she is in love with the master, so I don't see a reason for her to run away.
The point is that after being slave for a whole life removing her slavery status is not going to make her happy
it's kinda like doing one thing for a VERY long time and it ends up messing you when it's gone or something, right?
You could put it in that way, keep in mind that Daisy basically knows nothing about the life outside of it.
