I just recently arrived in Venice in Assassin's Creed 2 (PC version) and started the first mission where a man gives me and Leonardo da Vinci a quick tour of Venice. At the end, there is a cut-scene with a quick-time event. Leonardo da Vinci initiates a hug and the game prompts you to push a button. Seeing as it was a cutscene, I sat back not expecting this and watched until it was too late to hug him. Leonardo makes a sad face and walks away which made me feel like a jerk.
Does hugging or not hugging Leonardo da Vinci provide any benefits or penalties later in the game? Would it be worth replaying the mission (and how) for the other outcome? Can I save my bromance?
