It was a rather quick comment during a heated conversation with the Miz but the segments between Daniel Bryan and Miz always come so close to teetering between kayfabe and reality that it's hard to tell what's real or not at times. The comment in question came as a response of the Miz telling Bryan that he hurt his head and can't wrestle anymore.
Bryan responded by saying "I can't or they won't let me? We'll see in a year and a half and see what happens," thus alluding to his contract ending in 18 months and Bryan perhaps attempting to return to the ring in another promotion at that point in time.
The show even ended with Bryan saying "I wish I could say more" to Renee, leaving fans to wonder how much of this was a shoot and how much was in-character.
In my opinion, Talking Smack does such an excellent job of bluring those lines that it's almost impossible to tell and I believe it's mostly due to the fact that the show is not as heavily scripted as the rest of the WWE programming. Everything feels off-the-cuff and even when wrestlers are 'cutting promos' on each other, it seems very natural and more akin to their personalities.
