Amidst my search for Khan related material, I've recently learned something that maybe others here knew, but I sure didn't. Apparently there was a toddler among Khan's party at the Botany Bay. Apparently Chekov and Terrell first saw the child when they discovered the Bay on the surface of Ceti Alpha 5. For the rest of the movie the child is no longer seen, till the last moments of Khan's life on board the Reliant. The child toddles on up to the Genesis device, attracted by the pretty light, only moments before its destruction. Kind of weird, but interesting.

At first I thought it was a silly rumor and an altered picture, but then I found the second picture and the blog with the printed article about it. Crazy!
