There would be more mystical, symbolic imagery that might give him more of a sense of what's going on. I had wanted to strip away the gift for a long time and see if the show really played without it. But we got back into that". "A Single Blade
Single-entry single-exit Single-entry single-exit In graph theory, a single-entry single-exit (SESE) region in a given graph is an ordered edge pair ("a", "b") of distinct control flow edges "a" and "b" where: where a node "x" is said to dominate node "y" in a directed graph if every path from start to "y" includes "x". A node "x" is said to postdominate a node "y" if every path from "y" to end includes "x". So, "a" and "b" refer to the entry and exit edge, respectively. The first condition ensures that every path from start into the region passes through the region’s
