Like the title says, the early death of Jubair right before you are supposed to kill him.
Infiltrating the Madrasah Al-Kallasah
This is easy if you know how to do it. Have some guards chase you onto the roof. Then drop down to the door on the south side of the building. Engage in combat with the guards there. After a little while the guards on the roof will come down to the ground from inside the building. Since this is the only time in the game that the door is closed the guards' ai thinks they can go through. They will attack you through the door, which gives an opportunity to glitch inside by counter attacking. You need to be in combat with the guards outside since you can't lock onto the guards inside. Countering can be a little tricky because you might not be able to see the guards attack until it's too late.
Jubair's Early Death
Once you get inside you will find Jubair and the other scholars in the northwest corner of the building. They pretty much stay in the spot where they are (even grabbing and throwing won't move them). At the front of them are Jubair and the scholar he talks with during the scene. Now for pre-killing Jubair and/or the scholars. I've tried different killing combinations, each with their own results. First I killed everyone except the scholar Jubair talks with. Now for the scene... Levitating books?! Even the scholar I didn't kill doesn't appear for the scene, and the scene itself somehow won't end (when I had first originally done this I killed everyone and the scene ends as normal). Now I'll try killing just Jubair. You can identify him from the other scholars by the pouch he wears. Here's the problem with killing just him: You are exposed by the scholars, and the scene cannot start until you become anonymous. So glitch back outside the building the same way you came in. Lock onto one of the scholars so you are in combat and counter attack a guard who is outside. Then get far enough away that you escape the scholars and become anonymous (I had tried using a hiding spot but couldn't get out of it). Now for the scene... Wait, why is the scholar dead instead of Jubair?! When the scene ends you fail the mission as though the target had escaped. Now this is weird, the blade's low profile kill animation on the scholar is the same as on a target. Also one time I killed just the scholar and he still appeared in the scene as well as Jubair, but I failed the mission right after the scene ended. It's as though he is a copy of Jubair, and killing one of them affects the other. That's a very interesting thing in the game that can only be answered by Ubisoft.
Instant Kill
I wanted to try an automatic kill on Jubair like what I did with Garnier.

However I couldn't reanimate him because he can't be moved from the place he is. So I theorized it could be possible just by taking down his health with fists, since being knocked out isn't quite the same as being dead. Well it worked, but in a way that I didn't expect to happen. After I climbed up to start the scene and the dialogue appeared, "ancestor's memory synchronized recording..." Altair teleported to ground assassinate Jubair, causing the memory corridor scene to start. This is probably the only time in an AC game that a memory corridor scene has started before it should. It seems the game recognizes Jubair as a target when the scene starts. Afterwards the scene is cancelled. The invisible barriers are still there that prevent you from leaving, so I glitch my way through one of them by grasping a ledge. You aren't under city alert as you normally would, but can still complete the memory.

I put away my Assassin's Creed disc when Assassin's Creed 2 was released about 21 months ago. Shortly afterward, I lost the disc, and I was pretty much convinced that I would never see it again. Much to my surprise, I found the disc about a month or two ago, and I started playing it again a few days ago. It was nice to play Altair again...

Getting in the huddle of Sibrand's scene prior to the assassination is possible although it doesn't affect the assassination itself. Start by going to the docks then get on the boat close to the scene location. Jump to the spot by the stairs. Since this area is supposed to be unreachable you are able to walk right into the scene. There isn't much point to this besides some hilarity. During the scene I don't move the camera much since it follows Sibrand. Also I don't use memory glitches to zoom the camera in since that would make Altair disappear.

Jubair will not leave the building after the cutscene! Thanks to a few exploits you can get in the scene prior to the assassination and kill Jubair right before he teleports.
First of all, normally the ancestor's memory will start recording when you reach the roof of the building for the scene, but if you are detected that doesn't happen, with memory walls preventing you from going any further. There is a certain place on the west side of the building with a ledge that will lead you to a higher place on the roof, but getting to it is a little tricky. Get a guard to come after you to reach that place, then kill him to get rid of the memory walls. You want to hang on that ledge before he dies, so to delay his death I grab and throw him (I made the mistake of throwing him at a wall, which killed him faster). You need to be in the right spot to grab on that ledge when running up the wall.

Altair92's recent videos using the smoke bomb to cause targets to flee inspired me to revisit the first mission where I noticed this effect: Stefano da Bagnone. At the time, I couldn't find any interesting to do with the fact that he ran away - Ezio doesn't have a gun yet, and Stefano did nothing more than run along a path into the distance. But I recently found a particular mission design that causes Stefano to run in circles around the monastery. This gives an opportunity for a dynamic stunt, which is my favorite type of assassination, as many of you know.

Assassins are forbidden from using weapons inside their fortress with the exception of the training circle. The third tenet of the creed is to protect the Brotherhood, so Altaïr is not allowed into the fortress when Exposed or Unseen. Unless...

The Turkey Shoot: The goal in these assassinations is to immobilize the target so that you can easily stab him/her with the hidden blade. Of course, the developers never intended such assassinations to be possible, so you have to rely on several exploits in order to pull off these types of assassinations.
Here are video walkthroughs for the assassinations shown in "The Turkey Shoot".

Here are some extremes of hiding in plain sight.
William: After William is done lecturing his men, he goes to his desk to study a map. You can climb down behind William and blend right next to him. If you bump into the table, William will notice you, so you need to be careful as you approach the table. In this video, I line up Altair's shoes with William's shoes to ensure that Altair doesn't bump the table.
