Hey, I thought you guys were good at this stuff.
Well, just for the record:
When the smaller entity departs from its larger body, there is a shower of plasma balls which sparkle around for a few seconds, you cannot seem to move at this point, then the words "The End" appear, followed by, "Or is it...".
After this the game goes into the title sequence.
mutter, mutter, sure those EAB guys are good at spotting mystery screen shots......
