DaDrummer676 the way I thought up the pharmacy thing is that there is the main pharmacy, ta know desk bed sink what not, then there is within that room a large cupboard.
This cupboard is the storage room for the pharmacy and so has its own shutter, which is what Steph and Lillah are behind.
In my mind I assumed your character was in the pharmacy but obviously couldn't of snuck into the storage part because we closed the gate behind us (and its a relatively small room so not much sneaking could of happened.
Im not sure if this is how you saw it but thought id let ya know just in case :D
