Nah, so far, the story's pretty predictable, and it was like this since day 1. Most of us are pretty sure who the mystery long lost daughter is, and it was confirmed in this update, so unless the dev does a complete 180 for reasons, her identity's not much of a mystery anymore.
This one's a pretty interesting twist, but it could also be something trivial and not worth overthinking stuff. I suspect the old fart is the one responsible for this 'mystery', considering he admitted himself he didn't talk to his daughter for a whole year. He's prolly the stereotypical asshole who was pissed that he's daughter got knocked up by the MC who left her to give birth and raise a kid alone without giving a shit, so he tried to 'take care' of it. It could explain why Beth didn't talk to him for a year.
What kinda father does that ??
A real shitty one, like Olivia's dad, coz sadly, we have examples like that even IRL, a lot of them. And when the daughter started questioning him, he faked his supposed illness and quickly threw them out threatening to shoot them if they don't leave (!!). The old fart is my main suspect, but ofc, nothing's confirmed yet and future updates could prove he's innocent. Another one is Bob, MC's friend, coz he sure needs to answer a few questions about that 'detective'.
Another thing that kinda concernes me is the pics Anna took of MC's sis. Considering what Chloe's side hustle is, I wouldn't be surprised if the bitch tried to convince her to become an escort for pointless bullshit drama, but if that proves to be the case, I hope the MC can prevent it, coz being forced to watch an LI become a cheap slut for some $$$ isn't something I'd want to see in this game.
