Homeland Tropes

Watching Homeland and just noticed something that I guess is becoming a trope in TV shows about geniuses.  You are working on THE problem and you finally realize its hopeless so you start to clean up your life again.  In the midst of the cleanup you glance something out of the corner of your eye on a bulletin board, on your computer or in a photo that affirms you are not crazy, your contemporaries are wrong and you were right all along.
