I'm at 3:40PM... have syringe filled with sulphuric acid... have tried using both Victoria and Darrel to open van by using syringe with *lock*! They both keep saying, "I won't use it here." I must be missing something but what?!
Have explored old wing, mausoleum, chapel, garage, lab, clock tower, etc.
This is frustrating! I guess I'm just going to have to restore a saved game prior to giving Anderson the photo negatives and see if that makes a difference.
