Well, as many of us are all excited about the upcoming Assassin's Creed: Revelations alot of people (many noobs or newbies) want to have Altaïr Ibn-La'Ahad and Ezio Auditore somehow meet or talk in Revelations. Well, few days ago, I came up with a logical theory of how they could talk. Not meet, but talk.
As both Assassins had used the Apple in their life before (yes I know Ezio hidden it, but he was exposed to it many times in his life before) there could be some sort of side-effect causing each one to see visions of the future or past. So what if Ezio had a vison of the past and saw Altaïr, while Altaïr had vision of the future and saw Ezio? Now, what if Ezio were to say something to the Altaïr vision, and Altaïr heard what Ezio said through his vision of him. Same thing for Altaïr, if he says something, Ezio could hear it through that vision etc. And they could talk back and fourth through a vision of each other.
Yes, I'm aware there is a language difference (Altaïr: Arabic. Ezio: Italian/Latin). However, I tend to overlook this. Still, logical thoery, communitcation through visions. Post a comment to let me know what you think of this.
