Ah, there we are. So that was the cause of the super loud horn that was sounding off at the end of last weeks season premiere. Despite a billion different theories on who or what had set the horn off at Alexandria, it was revealed here that the noise was the result of a large truck crashing into Spencers sniper tower and having its horn jammed by the drivers corpse. At this point we were now well and truly up-to-speed with where things were when last weeks episode concluded and it only took 20 minutes to get there.
