A watery surface and what appears to be a light flickering.
Halations spread out.
Reichu: Incidentally, cut 002 bears only the vaguest resemblance to its storyboarded incarnation (see here and here). Before Sammael has even faded out, the red universe becomes an underwater scene of the “Primeval Sea” or “Soup of Life”. As the camera advances, “Angelic Script” (seen in the final cut) glowing light blue (not unlike the Tree) fades in and out. The angel fades out, then a glistening water surface and rays of light shining through enter the frame (a visual counterpart to the ED). The camera then begins to go towards the sun, breaking through the water's surface and being overtaken by the light. Finally, halations spread (as in the final version).
Eva tomo no kai has this to say about the left:
The same image of the flickering light appears in episode #16 (“Shi ni itaru, soshite”) and episode #20 (“Kokoro no katachi, hito no katachi”). Both times, it is just before Shinji's return to the real world from the entry plug (= the inner universe). Perhaps it is the image seen by an embryo inside its mother's womb of the light coming in from the outside world?
