One of the things I love about this game is the capacity it has to surprise me with things that I've never noticed in cards that I've looked at hundreds of times. I tend to theorize and speculate about the hidden clues far more than is healthy, so it was a joy to find something new that (as far as I know), no one else has noticed!
Take a look at the Chairman:

Take a closer look:
whoa. too close.
Pull back, and take a look to the left of him. Who is casting that shadow?
As far as I can tell, this is somebody new. Whoever it is has exposed (slightly sticky-uppy) hair and ears, as well as a slim physique and what look like armguards. Its a safe bet that I'll be looking for a match from now on!
I'm confused on which shadow you are talking about. The eye picture does nothing for me and I can see how the shadow on the wall might not be his, but it's not conclusive.
Long shot silhouette comparison: KNYFE - Rogue Agent has the requisite spiky hair and her gauntlet arm (if reversed and you squint a bit) could resemble the gauntlet.
But I don't think it works. KNFYE has no real story connection to the Chairman yet, and the shadow is certainly not a dead ringer for her.
