Just finished G1-3 and spoilers for the entire case:
Jesus this game is not holding back on the dark outcomes. I noticed the bloodstain was there but I kind of ignored it and thought I might have missed it. Then it turns out that he actually ended up doing it making him yet another guilty defendant... But you still get the not guilty verdict because this court is corrupt as fuck. I am loving the tone of this game and I feel Shu decided to go a darker tone to give it some distinction. I'm so excited to see the next 2 cases! I hope they are both full ones, though, well, they have been long just one really long investigation and one really long court battle so far.
