I realized a lot more on the second read. On the first one I totally missed how Iris was getting physically closer to Barry all through. I also missed the signs that it was not just Barry thinking Iris might figure out his identity as The Flash but that even at the start Iris was implying that she knew who he really was. The first read the Flash being Clark Kent seemed to out there. Even when I realized that Iris was right and the Grayson/Kent connection worked the Flash one was harder to believe.
