I just kinda noticed something odd with one of the screen shots... I might be the only one to see this but the second image with Terra in it looks very similar to the western part of the Lapis Ward...
I'm just speculating but if both images are actually from the same place, since both obviously look different maybe in Episode 12 we go... back in time to before the fall of Reborn or something? It wouldn't be the first time since something weird happened in the Citae Arc-d'Astrae when we meet Adrienn for the first time
AHHH IDK I'M JUST LOOKING FORWARD TO AME FINALLY GIVING US E12
