This could mean something or nothing at all. The top long picture is from the episode "The Major". When Liz is speaking to Judge Denner in chambers, in a split second these faces can be seen in the reflection of the glass in the door. It is the director and two unknown faces. The bottom left photo is an enhanced version of the photo Liz found in Red's secret apartment. The bottom right is a comparison of both photos. Could the third unknown face in the reflection be the same woman in the photo with Liz?
