About a certain dialogue option at start of act 1

At the start of Act 1 in your very first dialogue with Jocasta you get the option of getting jiggy with her. At least sometimes.

Even with Toybox I can’t figure out the conditions to get that option. All I can say is that it is not tied to the first big conviction choice during prologue. She happily sits on a heretic RT.

Is it based on the homeworld or what?
