Maybe Matt will use the paste and see Isaac? Isaac, after all, kind of became "the sacrifice the world demanded" if you like in S1 when he allowed himself to be killed. (It's why I felt a bit wary at one time about using the name isaac for a previous leader of the Others in my fic "The Man From Dharma", but then decided to go with it anyway.)

And why is it that the pretty always gets killed off in the first series - Boone, Isaac...
