I saw the promo too, and the way I see it? here goes. Casey goes off on the side mission right? and somehow without knowing it he commits treason. the FEDS find out, he’s imprisoned, Chuck and Sarah free him from jail and let him run. Thus bringing a risk on themselves for aiding and abetting a traitor(as it were) and getting kidnapped and ordered to hunt to Casey down dead or alive by Beckman.
