Peter Quinn has long been a favorite of mine. I wrote about him here, in a column from October 2014, as one of TV’s most interesting secondary characters. I like the ones who aren’t precisely second bananas or sidekicks, who have significant roles but who don’t necessarily propel the plot — and therefore can be much more interesting than your average hero or anti-hero. I love Doug Stamper on House of Cards; I love — loved– Peter Quinn on Homeland.
