Special Ending. Wowie Zowie.

[Whoareyou]

I had never heard about the scene where he "kills" him
But I had heard the "neither a cloud, nor a squall" which I believe might be what gets added when you have the Save the Queen

 

[Freyaa']

I have not done this yet, but I am gonna try the save the queen or hammer ending in aminiute :L
but I did hear that it just adds an extra scene into the play 'I want to be your canary' or something like that

 

[Solid Link]

Never heard of it but I'm gonna do my best to find a video of the scene and then post it.
