I'm trying to think of a way where I can double thread my companion mod so that the player could choose either a friend-based relationship or a romance based relationship through the quest. There are plenty of stages throughout the quest that could easily apply to a friend vs. a lover or both. Each stage that triggers a conversation would need a variable check but I have no idea how to do it in Skyrim. What kind of property would I need?
If the player takes the friend route it would set the boolean to 1 and the check at each stage would evaluate it. I'd have to put it in the quest stages.
