Brody Gets Angry Upon Discovering Walker Is Alive on 'Homeland' (VIDEO)

Did our own Michael Hogan retire the Brody-o-Meter too soon? Well, it isn't officially retired, but after this week's installment of 'Homeland' (Sun., 10PM ET on Showtime), it should definitely stick around for at least a while longer. The revelation that Walker is alive would seem to put Brody in the clear, but this thing appears to be way more complicated than that. We already know Brody can pass a lie detector test, so when Carrie told him Walker was alive, sure he seemed shocked, but that could have been another lie, like his fidelity to his wife. But the clincher at the end revealed a truth of sorts. !!SPOILER ALERT!!
