I finished the game.
-SPOILER-
After the cutscene where you were holding on to the life boat that was going to the surface, I saw Ealenor in the daylight. She got this needle thingy and injected it into me, and said I became her concience. Then she went over to the ledge and said some stuff, then the Little Sisters gathered around her, and the one at the intro video gave her the doll of your character, and then she dropped it in the water, saying something about the Rapture nightmare being over.
-SPOILER-
I heard there were 4 endings..
Very Bad, Bad, Good, Very Good.
I didn't watch that video because I didn't want to get spoilers for what ending I got.
Anyone that watched that video know which one I got?
