Thank you for the hint. I was able to get there. I also found a route where there is a scene between Lou and Ben, but I feel that am still missing one scene with Bo. I only have three scenes with him... and one last interrogation mark to beat the game ;-)
Really enjoyed the game, both the story and the art!! I was wondering if I could get help for the scene column 1 row 3. ;-) I assume it is attached to Bo's storyline.
