Glad you think so Anon. And, well, the whole point of the Southgate mission is to get on good terms with the natives after all. ;) Got to admit that I hadn't really thought about the eagle vision issue before. This Connor does certainly have naturally attuned senses due to years of hunting, etc... My thinking is that he is still a descendant of Altair, just not a particularly close relation of Haytham's (similar to how Ezio is both Desmond and Clay's ancestor, even though the two of them aren't 'relatives'). So, he probably does have it still, we'll just have to wait and see.

Sorry for the rather rambling reply. (Part 2 should hopefully be ready in the next couple of days).
