Well after the storyline change in episode 8, their were few problems in episode 9, like where Saeko got the katana from? Where do they ride after the Emp event? and lastly why do they have a back entrance?(knowing this, question how they fend off the zombie at the back if nobody is there?) these are the Plot Hole I see in this alternate story. Well at least they add a bit scene on Saeko dark past and the secret kissing scene(that make me relief from my anger and hatred to the alternate story). At least they put the story back on track.
