^ No worries. I got a bit carried away also.
How many Metropolis citizens actually saw Superman close enough to get a lastly impression of him? Not many. I didn't see any news crews or people taking photos. So at present, Superman can only be identified by the military members who worked with him and a dozen or so people in Metropolis who actually saw Supeman when he wasn't fliying around battling Zod at super speeds.
Okay, fair point, but especially after all the carnage in Metropolis, surely people worldwide will demand Superman give a public interview and show his face? Even if Clark isn't particularly at risk for recognition at the end of MOS, that can't possibly last.
