How does one take the alternate routes with the secretary and the crazy lady? (forgot their names at the moment, different device)
In the latter's case, I remember seeing other options, but they were greyed out and I couldn't click them. I don't recall even seeing such for the secretary, but then again it has been a while since I last played.
I know there's more for these characters, as I can see the scenes in the images on this page, but I don't know how to get them.
