The Hidden Blade Assassin's Creed in Depth

By reading the title you can probably guess what the video is about. The first time you meet the thief guild leader Antonio (not to be confused with Antonio Maffei in Tuscany) is in a scene sequence 7 in Venice. Here's the basic setup of what I do:

1. When you first arrive at the thieves guild in the game there's a scene with the boat arriving. Right afterward I move away from the boat to avoid another scene. There are three thieves prestaged outside the guild (and if you look in through the window you can see Antonio in the building).
2. Leave the area. If you get far enough Antonio will no longer be there when you come back.
3. Go back to the boat to start the scene. I also placed two unconscious bodies on a table to make things look more amusing. At first it looks as though nothing has changed, but when Antonio is supposed to appear he doesn't. So basically it's a whole scene without Antonio.

Some more things to note. You can move the prestaged thieves by attempting to grab or attacking, but they will walk back to their prestaged places. It is possible to move them into water so that they also won't be in the scene, but that will take a while. Also when you leave the area before starting the scene Ezio cannot be detected. The game forces you to become anonymous.

Edit: Here is what the scene would normally look like.
