What was that I saw?

Can someone verify what I just saw? When Christian tells Sun that " got a bit of a journey ahead of you" as he is showing her the picture from 1977 and there is a close up shot of her 'surprise face'- right before the scene cuts away to 1977- there is someone back in the shadows on the right side of the screen, over Sun's left shoulder. Is that an error? Or does it look like someone with RED HAIR???? Does anyone else see this?
