Oddly enough, the fact that he called her Tia was the thing I noticed most about last chapter. Now I'm wondering why he hasn't said something about her still calling him "your grace"...
I still want to know HOW Tia distracted or sent away Alphonse, but I suppose it's not necessarily important to the story. My sister and I were speculating about how Tia's relationship with Alphonse will change now; will he still obey her, or will he be more suspicious?
Further, we are looking forward to how Tia has to start adjusting her plans. Any foreknowledge she had from the previous timeline is going to be changing now that certain people have been removed and the politics are switching up. And will she start acknowledging Cedric's feelings enough to plan around them properly, since she clearly missed that in this plan? Even if she feels she needs to keep him at arm's length for The Saintess later, she still needs to face reality to properly predict and manipulate Cedric's actions...
