I notice that, while Bonnie in-game only appears in Night 1 as a character you see, she has this image in the files, labelled "b02" in "b_scenes"... Is there a hidden scene with her or something?
Sorry to disappoint you, but this scene hasn't been added to the game yet. I had planned to add it to this version, but I couldn't. It will be in the next one.
Because it would be cool if, say, if you go back to the office after cleaning at least 1 table, but not all 3, then you get ambushed by her as was Freddy's plan.
It would be something to be added in the second night, but, hey, this is really a good idea. I will try to add a scene of her in the first night after cleaning some tables.
