Wow, thank you! I tried that, and it worked, I got the ending. You should add this to the guide, that way you'll help others too.
Maybe I didn't ever get an ending after all. Maybe there isn't another ending besides the one you've mentioned. I just went to the hospital after collecting all effects and couldn't kill anybody out there or progress any further. So I thought that was it, seeing his parents at the hospital. I didn't know I had to catch the bird first.
