6. The Iron
Episode credits are usually dripping with hints and teasers, from locations to items to incidents yet to happen. In this case, a yet-to-be-seen-in-action weapon is given its debut.
The iron, presumably used by Negan to scar Dwight's face, is heating up in the furnace. Fans haven't actually seen Negan branding his top man, but that is exactly what happened and presumably not for the first or last time.
The fact that the iron is sitting in the credits could be a simple nod to the past or it could be a very ominous threat for the future of one (or more) character(s). What do you think?
