In the scene where Buck and Eddie share a hug, a tattoo is clearly visible on Buck's wrist. This tattoo does not appear anywhere else in this or any other episode.
Maddie says that a dispatcher from Portland, reported that someone called from a 'spoofed' number. This is not possible when calling 911. E911 services have a direct link to the telephone company METADATA, which 100% gives the real number dialed from. E911 Systems, ignore the displayed caller ID, and always show the real one, even if *67 is used to hide it.
