Playing a rogue, I happened upon a scroll of blink and a gated area with no keys. I used the scroll of Blink to enter into the cage/cell and at that point I was unable to continue as I had no way of getting out. This isn't a complaint, merely inquiring if it's an oversight. Perhaps it'd be wise to either have a switch on the inside of the cell to open the door or perhaps make Blink not work for the aforementioned purpose. Then again, could keep it as is and merely have it as a lesson for players to not attempt such things unless you have TWO scrolls of blink.
