It's hard to explain without giving away how I know this. But as I said earlier, come October you will see at least most of what is reported here happening exactely as mentionned, including Daryl taken prisoner, the jumpsuit everything, the the introduction of the Negan's sanctuary will be having Daryl as the "guest" as what they did with the Michonne and Andrea in Woodburry. Later they will parade him in Alexandria in the jumpsuit, and make Rick hold Lucille..etc. These things will happen if that's what you're asking.
