Quinn Returns in New Trailer for 'Homeland' Season 6

It's ridiculous for Quinn to still be alive frankly, but I'm with Homeland til the bitter end at this point. Even if they did jump the gun with their optimism in predicting a female president (and this is not an optimistic show, which makes it even more bittersweet). But really, Quinn can't possibly be mobile this season. And his entire role on the show was as the action hero Jack Bauer type, so what are they going to do with him? I know they didn't want to get rid of Rupert Friend, but I can't imagine the use of a debilitated Quinn, can you?
