To start I'm a huge fan of Chuck. I've watched all the seasons like 8 times already. But now to the comeback! I believe it should come back as a 13 episode final season. My reason is because, like Season 1 and 5, a lot happened in 13 episodes. The same can happen again. Like possibly there is still one last Intersect out there that Orion (Chuck's dad) left and they can help get Sarah's memory back with. That is just one idea of many I have. But like I said a lot can happen in 13 episodes. Who knows.... I just want closure and I bet many of you probably agree!
