Did anyone notice when...
...the black smoke was being stared down by Eko, and the camera panned through the body of the smoke, there were flashes of lightning that revealed images from the flashbacks of Eko's life in that episode? The church with the cross on its roof, the old man with his head down, ready to be shot, Eko's brother (I think) with the pistol being handed to him, a mysterious woman standing, Eko holding his brother in his arms after he was shot, and finally, a statue of Jesus on the cross.
Did anyone else see those?
