Yeah, the quest tracking and event triggers need to be updated and improved for sure. (It should also be more clear when making a choice might lock you out of alternate stuff; there are some branching paths which have more outcomes than folks might think.)
I'm gonna assume you either responded to the wrong comment or you're just trying to troll and bait me. Either way, there are scene variations with several characters (though mainly Michelle) depending on certain choices you make. The post of mine you quoted and the person I was responding to wasn't even referring to Lisa in the first place.
