I don't like being an asshole or rude to video game characters, so when it comes to Lindsey's dialogue which has her face in blue, what does it exactly lead to? Does our character begin to blame himself for her attempted suicide? Anything more?
At the moment jack squat. Like Mill1o said there are only a couple unique dialogues you can select and technically a hidden quest where you can either beg forgiveness from Lindsey or double down on being a dick and loose a lot of potential interactions. You also earn the ire of a great chunk of the community if they learn you engaged with it. It is currently unclear if they even intend to continue this route or if has become more of a proof of concept at this point.
