Sequence 6 - Road Trip
We are going back to the town  to Lorenzo. 
Now, go to the Leonardo's workshop. Unfortunately he's not at his home at the moment.  Use horse to follow your friend (go to the mountains).  When you will be at your destination, approach the cart and help the painter.
Sequence 6 - Romagna Holiday
Unfortunately, it will appear that your enemies are chasing you. Soldiers will try to jump on a coach - get close to the rocks and try to throw them off.  When an enemy will manage to climb on a coach, turn left and right trying to knock them off (be careful to not fall down).  If this will not help throw them off manually (by pressing KÓLKO).
At the same time try to avoid any obstacles. At some point, you will have to cross over a burning bridge - fiery arrows could be a problem too.  When you will get back to the river, Ezio will decide to deal with opponents. 
A good idea is to catch opponents (CIRCLE) and cut their throats.  Soldiers equipped with armor should be killed in another way - press X when they will attack SQUARE (without holding R1).  After the battle run to the bridge.
You are in Forli.  Go to Leonardo, who is standing near the ship.  Speak with him.
Sequence 6 - Tutti a Bordo
We have to save a lady trapped on the island. Take a boat located nearby.  Sail to Caterina (using a paddle - CIRCLE and Left Analog Button). 
Take woman to the docks.  She will help with a chat with the captain.  Go to the ship and sail to Venice.
