At the start scene where Daryl kills the bikers with the rocket launcher theres a few frames where you can see a vehicle driving into the background. This could have been a production error, or could it be Negans men seeing the incident?
Also theres speculation that Daryl getting injured in the back specifically on the wing on his jacket is foreshadowing of him having his wings clipped, prior to his death?
For me personally i love this level of detail they throw into the series, some of it is red herring material for sure to throw people onto the wront scent, time will tell
