Chuck seemed to imply that there is a solution, but  not with  the Imprison Chuck plan they were going to do, nor with Chuck's intended end. The difference is this time, Castiel is not in a box crazed by the Mark, He is with them. Sounds like he needs to be around to heal a bunch of people. Maybe the brothers won't be alone this time, and have a lot of help.

Here's a thought, what if Jack needs a vessel now? What if he and Castiel combined?
