The denial is strong.
First Joe investigated Wells and now Iris. Wells secrets will be revealed.
I am pretty sure that it has not so much to do with denial as with people just not caring enough to invest much time into speculating. It is a show that has a lot of fans but you have to differentiate between people who watch it once a week because it is like any other entertaining show to them and then people who geek out over every single easter-egg in the episodes.
It is generally interesting (and annoyingly childish) how the people here, who have been insisting on the prediction that RF being Wells (which has turned out right, as seen in this ep) are rather haughty and condescending to people who seem surprsied or are still not totally convinced.
You made a good guess, that is all, nothing you have to be too proud of, you didn't archieve anything by this (other than you can now point at others who haven't agreed with you and "Na na na na nah, I told you so"). Some have seen it coming, other didn't. People who haven't aren't idiots for not doing so, I am pretty sure it was the intent of the show-makers to keep it a secret.
And, of course, you can argue that it was so damn obvious from the beginning but still, not everybody takes everything on face value.
A forum like this should, and most likely was intended to, be a place where you can discuss your ideas without being riddiculed for them.
