Hey,
I've been stuck for a while inside Dr Sigmund's Orphanage, during the 'prison break'. I already talked to literally everyone / everything inside of the building.
Below are a few screenshots to illustrate where I am: http://puu.sh/lrafo/6ebf73a187.png http://puu.sh/lrajA/93370c1561.png The 4 doors downstairs. (to the bathrooms, Dr. Connal's library and the Lower-Level arena are locked)
