I think the reason we see more of that in Mark's route is because it was the one that got the most updates so far. Personally, i really like the intrigue as to what even are Virgil's intentions with this, but i don't expect to learn anything until much further in development still. At this stage though, i do think the story is intentionally vague so as to leave us guessing and trying to figure things out on our own. Which, understandably, can feel a bit uncomfortable since we have to wait for new updates to get more pieces of the puzzle.
