Is this extended ending the same for each of the 5 endings or are each of them unique? I already got the Good Ending on my first playthrough so it would REALLY suck if I have to re-earn that ending with the photos just for that extended ending. Also, do you get any extended scenes or anything if you collect all the child's drawings or anything else I should know about?

It's only for the good ending. The child drawings don't effect it.

The extra-scene is like 10 seconds long. You better watch a video on Youtube or something...

Do you have a source? How do you know? This really puts a wrench in my plans.

I know because I played the game before.
