I'll make a comment on Mark's behavior. As it is actually for the most part really in a genius way explained, mainly at the conflict between Mark and Cathy. First Mark's circumstances are quite different from the first run as he confesses his situation very early on and overall he is in a much more stressed state just on average. Because of this I think he develops a sense of moral highground its not explicitly stated but this is what I think, he tells everyone his situation but nobody is returning the favor and is still just lying to him causing him to act the way he does. He even in the conversation with Cathy manipulates the conversation so that Cathy gives advice that she necessarily can't follow through on herself. He is absolutely in the wrong here but I love the way this feels so real and built up and the resolution that happens because of it feel's so good. It's a great way to show how the slight change affects our characters and their relationships. Loving the playthrough btw
